SAJ H2 10kW Hybrid Inverter Price in Pakistan — Complete Review
MartOnline 16 min read
When a Pakistani home outgrows an 8kW inverter but does not yet need a full 12kW system, the SAJ H2 10kW is the answer. It sits at the upper end of the SAJ H2 single phase LS2 series, powerful enough to run two air conditioners alongside all household appliances simultaneously, yet still a single phase inverter suited to the residential electricity connections found in most Pakistani homes up to 10 marla.
This review covers the complete picture before you spend your money. Full specifications from the official SAJ datasheet, real load calculations for larger Pakistani homes, compatible batteries, installation guidance for Pakistan's climate and a side-by-side comparison with the 8kW and 12kW models. Read this first.
What Is the SAJ H2 10kW?
The SAJ H2 10kW is a single phase low voltage hybrid solar inverter from SAJ Electric. It is sold in Pakistan as the H2-10K-LS2 model from the LS2 series, the same platform as the SAJ H2 6kW and SAJ H2 8kW, but with the highest output capacity in the single phase low voltage range before stepping up to the 12kW model.
The SAJ H2 10kW manages solar panels, battery storage and the grid simultaneously and automatically. During daylight hours it runs your home on solar, charges your battery with surplus energy and optionally exports to the grid through net metering. When load shedding hits, it switches to battery power in under 10 milliseconds. During load shedding with solar generating, it runs your home directly from panels while simultaneously recharging the battery. No manual intervention needed at any point.
For larger Pakistani homes and small commercial properties that need more than 8kW but want to stay on a single phase inverter, the 10kW is the most capable option available in the SAJ H2 LS2 range.

What Appliances Can the SAJ H2 10kW Run?
The SAJ H2 10kW has a rated output of 10000W. Here is a realistic load breakdown for a larger Pakistani home:
Typical 8 to 10 marla home load:
| Appliance | Approximate Load |
|---|---|
| 1.5 ton inverter AC (x2) | 2800W |
| Refrigerator | 150W |
| Ceiling fans (6) | 300W |
| LED lights | 100W |
| Television | 80W |
| Water pump (intermittent) | 750W |
| Washing machine (occasional) | 500W |
| Router and misc | 50W |
| Total without pump and washing machine | 3480W |
| Total with pump running | 4230W |
| Total with pump and washing machine | 4730W |
At 4730W with all appliances running simultaneously including two 1.5 ton ACs, a water pump and a washing machine, a large Pakistani home sits comfortably within the 10kW capacity with over 5000W of headroom remaining. Even on the heaviest summer days in Karachi or Lahore with both ACs at full load, total simultaneous consumption for a 10 marla home rarely exceeds 6000W to 7000W.
Small commercial property load:
| Appliance | Approximate Load |
|---|---|
| 2 ton inverter AC (x2) | 4000W |
| Computers and monitors (5) | 750W |
| LED lighting | 200W |
| Server or NVR | 150W |
| Printer and misc | 100W |
| Total | 5200W |
A small office or shop with two 2 ton ACs, computers, lighting and equipment runs at approximately 5200W simultaneous load, well within the 10kW capacity. The SAJ H2 10kW is a practical choice for small commercial properties with single phase electricity connections and moderate commercial loads.
What the SAJ H2 10kW cannot handle:
Three air conditioners running simultaneously alongside a full household load, heavy industrial motors or large commercial kitchen equipment would push toward or beyond 10kW. For these requirements, the SAJ H2 12kW single phase or a three phase model is the appropriate choice.
Who Is the SAJ H2 10kW Best For?
Ideal for:
- 8 marla home with two 1.5 ton ACs
- 10 marla home with heavy household load
- Small office with single phase connection
- Small shop or clinic with two ACs and equipment
- Homes with monthly electricity bills of Rs 40,000 to Rs 80,000
Consider the SAJ H2 8kW instead if:
- Your home is 5 to 7 marla
- You run only one 1.5 ton AC
- Your total simultaneous load rarely exceeds 6500W
- Your monthly electricity bill is below Rs 35,000
Consider the SAJ H2 12kW single phase instead if:
- Your home is larger than 10 marla
- You run three or more ACs simultaneously
- You have heavy commercial equipment alongside household load
- You want maximum single phase capacity with the most headroom
SAJ H2 10kW vs SAJ H2 8kW vs SAJ H2 12kW
| Feature | SAJ H2 8kW | SAJ H2 10kW | SAJ H2 12kW |
|---|---|---|---|
| Rated Output | 8000W | 10000W | 12000W |
| Max DC Input | 16000Wp | 20000Wp | 24000Wp |
| DC Oversizing | 200% | 200% | 200% |
| Max DC Current | 20A per MPPT | 20A per MPPT | 20A per MPPT |
| Best Home Size | 5 to 8 marla | 8 to 10 marla | 10 marla to 1 kanal |
| ACs Supported | 1 to 2 ton | Two 1.5 ton | Two 1.5 ton or larger |
| Warranty | 5 years | 5 years | 5 years |
The 10kW sits exactly between the 8kW and 12kW in every meaningful specification. The step up from 8kW to 10kW adds 2000W of output capacity and 4000Wp of additional solar input. The step up from 10kW to 12kW adds another 2000W and 4000Wp.
For Pakistani homes where two ACs will run simultaneously but three ACs are unlikely, the 10kW is the most cost-effective choice. If you plan to add a third AC or your household load is consistently heavy, invest in the 12kW from the start. Upgrading an inverter later is significantly more expensive than choosing the right size initially.
Compatible Batteries for the SAJ H2 10kW
The SAJ H2 10kW works with low voltage lithium batteries in the 40V to 60V range. MartOnline stocks three compatible options:
The natural pairing for any SAJ H2 inverter. Plug-and-play CAN communication means no additional configuration. With over 8000 cycle life and 95% usable depth of discharge, a single 16kWh SAJ EK30 B3 provides solid backup for a large Pakistani home. For homes with two ACs running during load shedding, consider starting with two 16kWh batteries in parallel to extend backup duration. Up to 16 units can be connected in parallel for a maximum of 256kWh total storage.
10000 cycle life makes this the longest-lasting battery option available from MartOnline. Compatible via CAN 2.0 and RS485 protocols. Built-in casters simplify installation. For buyers who plan to run a high-load system and want maximum battery longevity, the Sunwoda Atrix Max Plus is the premium choice. Up to 32 units can be paralleled for very large storage requirements.
Designed for the Pakistani market with 6000 cycle life and 10kW maximum discharge power. Compatible with the SAJ H2 10kW via RS485 and CAN. A practical locally supported option. Note that the Mesol's 10kW maximum discharge power matches the 10kW inverter's full rated output, making it a well-matched pairing for this specific model.
How much backup will you get?
With a fully charged 16kWh LiFePO4 battery and 95% usable capacity:
- Usable energy: 15.2kWh
- At 2.5kW load (fans, lights, fridge, TV, one AC off): 15.2 divided by 2.5 = approximately 6 hours
- At 4kW load (one 1.5 ton AC plus household): 15.2 divided by 4 = approximately 3.8 hours
- At 6kW load (two 1.5 ton ACs plus household): 15.2 divided by 6 = approximately 2.5 hours
For Pakistani homes running two ACs during load shedding, two 16kWh batteries in parallel (30.4kWh usable) doubles these figures:
- At 4kW load: approximately 7.6 hours
- At 6kW load: approximately 5 hours
For cities with 6 to 8 hours of daily load shedding, two batteries paired with the 10kW inverter and a large solar panel array provides comfortable whole-day coverage even with two ACs running.
Solar Panels for the SAJ H2 10kW
The SAJ H2 10kW accepts up to 20000Wp of solar panels across 2 independent MPPT inputs, each handling up to 20A of input current with a maximum of 500V DC.
For a practical Pakistani installation using 550W panels:
- Per MPPT: strings of about 6 to 8 panels, depending on panel voltage, always kept below the 500V limit
- Recommended total: 20 to 30 panels
- 20 panels = 11000Wp
- 24 panels = 13200Wp
- 30 panels = 16500Wp
The 200% DC oversizing allows up to 20000Wp of panels on a 10kW inverter. For larger Pakistani rooftops with enough space for 30 or more panels, the 10kW inverter can maximise energy harvest throughout the day. More panels mean faster battery charging, more surplus energy for net metering and better performance during cloudy conditions in Pakistan's monsoon months.
Three Operating Modes
Self-Consumption Mode
Solar runs your home first. Surplus charges the battery. Battery supplements when solar is insufficient. Grid is used only as last resort. This is the recommended mode for most Pakistani homes and small businesses as it minimises electricity bills while keeping the battery ready for load shedding.
Backup Priority Mode
The inverter keeps the battery as full as possible at all times. Grid electricity tops up the battery when solar is insufficient. Useful for properties in areas with very unpredictable or extended load shedding schedules where maximum battery readiness is the priority at all times.
Time of Use Mode
Charges the battery during off-peak tariff hours and discharges during peak hours. Relevant for commercial properties where time-of-use electricity pricing applies to the electricity connection.
Complete System Guide for SAJ H2 10kW
A complete 10kW hybrid solar system for a large Pakistani home or small commercial property includes four main components:

Installation Tips for Pakistan
Inverter Location
The SAJ H2 10kW is IP65 rated and suitable for indoor or sheltered outdoor installation. The ideal location in a Pakistani property is a utility room, garage or covered area protected from direct rain. Avoid direct exposure to monsoon rain even with IP65 protection. At 10kW output the inverter generates more heat than smaller models, making ventilation especially important.
Ventilation
Leave at least 30cm of clear space above, below and on both sides of the inverter. At full 10kW output in Pakistan's summer heat, the inverter's cooling fan runs frequently. Good airflow prevents thermal derating where the inverter reduces output to protect itself. Never install the 10kW in an enclosed space without dedicated ventilation.
Avoid Direct Sunlight on the Inverter
Do not mount on a south or west facing wall receiving direct afternoon sun. Wall surface temperatures in Pakistani summer can reach 60 to 70 degrees Celsius on sun-exposed surfaces. A shaded north or east facing wall is always the better choice.
Battery Placement
For a two-battery setup, both batteries should be placed in the same location close to the inverter. Keep DC cable runs short and equal length between batteries to ensure balanced charging and discharging. The SAJ EK30 B3 and Mesol 16kWh Infiniti are designed for indoor floor installation. The Sunwoda Atrix Max Plus has built-in casters for easy positioning. Confirm the floor can support the combined battery weight before installation.
Earthing
Proper earthing is critical for safe operation of a 10kW system and is checked as part of net metering approval. At higher power levels, a proper earth connection is even more critical than on smaller systems. Insist your installer provides and verifies the earth connection before commissioning.
Cable Sizing
A 10kW inverter draws significantly higher currents than 6kW or 8kW models. The AC cables between the inverter and your distribution board must be correctly rated for the inverter's 45.5A maximum output current. Undersized cables on a 10kW system cause greater energy losses and safety risks than on smaller inverters. Do not compromise on cable quality or sizing.
Generator Integration
The SAJ H2 10kW supports generator input. For larger Pakistani homes and small businesses with existing generators, the inverter manages generator power automatically alongside solar and battery, reducing fuel consumption while maintaining full backup coverage during extended outages.
Wi-Fi Monitoring
Connect the SAJ H2 10kW to your home or office Wi-Fi during commissioning for access to the eSAJ monitoring app. At 10kW scale, monitoring becomes more important as the system is managing more energy and higher loads. Real-time visibility into battery state, solar generation and consumption helps identify inefficiencies and catch faults before they become problems.
Net Metering
The SAJ H2 10kW is designed to meet NEPRA's technical requirements for net metering. A 10kW solar system with 20000Wp of panels generates significant surplus energy during low-consumption hours, making net metering credits particularly valuable at this system size. Register with your local DISCO at the same time as installation.

Frequently Asked Questions
What is the price of the SAJ H2 10kW hybrid inverter in Pakistan?
SAJ H2 10kW prices in Pakistan change regularly due to import duty adjustments and currency fluctuations. Contact MartOnline via WhatsApp for the current PKR price and a complete system quotation. We stock genuine SAJ H2 10kW inverters with full warranty and can advise on compatible batteries including the SAJ EK30 B3, Sunwoda Atrix Max Plus and Mesol 16kWh Infiniti for your specific home or business load requirements.
Can the SAJ H2 10kW run two air conditioners simultaneously during load shedding?
Yes, the SAJ H2 10kW is designed to handle two 1.5 ton inverter ACs running simultaneously alongside other household appliances. Two 1.5 ton ACs draw approximately 2800W combined. Adding a refrigerator, fans, lights and other appliances brings total simultaneous load to approximately 3500W to 4500W, comfortably within the 10kW rated capacity. For two 2 ton ACs the combined draw increases to approximately 4000W, still well within the 10kW limit with significant headroom for other appliances.
How many solar panels can I connect to the SAJ H2 10kW?
The SAJ H2 10kW accepts up to 20000Wp of solar panels across 2 independent MPPT inputs with 20A per MPPT and a maximum of 500V DC. In practical terms you can connect 20 to 30 panels of 550W each for a total of 11000Wp to 16500Wp. The 200% DC oversizing means connecting panels rated above 10kW is standard practice, ensuring the inverter operates at full rated output for more hours of the day and maximises energy harvest during Pakistan's limited peak solar window.
How many batteries do I need with the SAJ H2 10kW?
For a large Pakistani home running two ACs during load shedding, two 16kWh LiFePO4 batteries in parallel is the recommended starting point. With 30.4kWh of usable combined capacity, two batteries provide approximately 5 to 7.5 hours of backup depending on your total load during outages. A single 16kWh battery provides around 2.5 to 4 hours at typical 10kW system loads, which may be insufficient for 6 to 8 hour load shedding periods without solar simultaneously charging the battery.
What is the difference between the SAJ H2 10kW and the SAJ H2 12kW single phase?
The SAJ H2 12kW single phase delivers 12000W versus 10000W and accepts 24000Wp of solar panels versus 20000Wp on the 10kW. The 12kW is the better choice for homes with three ACs, very heavy household loads or small commercial properties where peak consumption regularly approaches or exceeds 9000W. For most 8 to 10 marla Pakistani homes with two ACs, the 10kW provides comfortable capacity at a lower price point than the 12kW.
Is the SAJ H2 10kW suitable for a small office in Pakistan?
Yes, the SAJ H2 10kW is well suited for small offices with single phase electricity connections. A typical small Pakistani office with two 2 ton ACs, five computers, LED lighting, a server and miscellaneous equipment runs at approximately 5000W to 6000W simultaneous load, comfortably within the 10kW capacity. The generator support feature is particularly valuable for commercial applications where power continuity is important and an existing generator is already in place.
