Sunwoda Atrix Max+ 16kWh Battery — Complete Review 2026

The Sunwoda Atrix Max+ (model Atrix Max-16L-PK) is a 16kWh LiFePO4 residential battery manufactured by Sunwoda Energy, a subsidiary of Sunwoda Electronic Co., Ltd., one of China's largest battery manufacturers by production volume. At Rs 600,000 from MartOnline it sits between the SAJ 16kWh at Rs 580,000 and the Mesol 16kWh at Rs 635,000 — but its specifications justify the premium over the SAJ in ways that matter for serious long-term solar installations in Pakistan.

The Atrix Max-16L-PK carries three specifications that no other 16kWh LV battery in MartOnline's catalogue can match simultaneously: 10,000 cycle life, 16kWh of usable energy at 100% DOD, and 11.2kW of both charge and discharge power — the highest power rating of any battery reviewed here. For Pakistani homeowners who plan to cycle their battery daily for 15 to 20 years and want maximum energy and power from a single unit, the Sunwoda Atrix Max+ is the premium choice.

This review covers all specifications from the official Sunwoda datasheet dated 20260514, real backup calculations, and an honest three-way comparison with the SAJ 16kWh and Mesol 16kWh Infiniti.

What Is the Sunwoda Atrix Max+

The Sunwoda Atrix Max+ (Atrix Max-16L-PK) is a Pakistan-specific variant of Sunwoda Energy's Atrix Max residential battery series. The "-PK" suffix in the model name indicates this is the Pakistan market version, a detail confirmed on the official datasheet header. Sunwoda Energy is a division of Sunwoda Electronic Co., Ltd., headquartered in Shenzhen, China, with battery manufacturing operations supplying automotive, consumer electronics and energy storage markets globally.

The Atrix Max+ is positioned as Sunwoda's premium residential battery for the Pakistani market — combining the highest cycle life, the most flexible installation options (floor or wall), integrated WiFi monitoring, and built-in casters into a single product. Its design brief is maximum performance and maximum flexibility for buyers who want the best available 16kWh battery and plan to keep it for the long term.

The official datasheet lists four core advantages: Excellent Performance (10,000 cycles, DC switch), Flexible Application (32-unit scalability to 512kWh), Minimalist Structure (casters, compact high energy density), and Intelligent Management (real-time monitoring, remote maintenance via WiFi).

Five Specifications That Set the Sunwoda Apart

1. 10,000 cycle life — the highest available

The Sunwoda Atrix Max+ is rated for 10,000 cycles using safe LFP cells, as stated on the official datasheet. At one full cycle per day — the typical pattern for a Pakistani home cycling its battery through daily load shedding — 10,000 cycles represents approximately 27 years of daily use. This is 25 percent more cycles than the SAJ 16kWh (8,000 cycles) and 67 percent more than the Mesol 16kWh (6,000+ cycles).

For Pakistani homeowners who plan a long-term solar investment and want to maximise the usable life of their battery before replacement, the Sunwoda's cycle advantage compounds significantly over time. A battery replaced at 8,000 cycles costs Rs 580,000 to Rs 635,000 to replace. Delaying that replacement by 2,000 additional cycles represents meaningful long-term cost savings.

2. 16kWh usable at 100% DOD — more energy per battery

The Sunwoda Atrix Max+ datasheet explicitly states 16kWh usable energy at 100% DOD test conditions (0.2C, 25°C). The SAJ 16kWh states 15.2kWh usable at 95% DOD. The difference of 0.8kWh per battery is approximately 32 additional minutes of backup at a typical 1.5kW essential load — a meaningful real-world difference when battery level is dropping toward the end of a long outage.

At real-world temperatures in Pakistani summer (35°C to 45°C ambient) both batteries will deliver slightly less than their rated usable capacity. However the Sunwoda's starting point of 16kWh at 100% DOD means it retains a usable capacity advantage over the SAJ's 15.2kWh even after temperature derating is applied.

3. 11.2kW charge and discharge power — fastest and most powerful

At 220A maximum charge and discharge current and 51.2V nominal voltage: 220 × 51.2 = 11,264W — approximately 11.2kW in both directions. This is the highest charge and discharge power rating of the three batteries in MartOnline's 16kWh range.

The 11.2kW charge power is particularly significant. The SAJ 16kWh charges at only 8kW, meaning a 10kW or 12kW inverter is bottlenecked by the battery during charging. The Sunwoda charges at 11.2kW — fast enough to keep up with a 10kW inverter at full charging capacity and near full capacity on a 12kW inverter.

For homes with heavy daily cycling and a limited solar window for recharging, the faster 11.2kW charge rate means the battery reaches full charge earlier in the day, leaving more time for net metering export or solar-direct consumption before sunset.

4. 32-unit parallel — scalable to 512kWh

The Sunwoda Atrix Max+ supports up to 32 units in parallel, providing a maximum combined storage of 512kWh. This is double the 16-unit maximum of the SAJ 16kWh and Mesol 16kWh (both capped at 256kWh).

For residential users the difference between 16 and 32 units in parallel is rarely relevant — a 10 marla home off-grid requires 4 to 8 batteries, well within both limits. However for commercial properties, large farmhouses or multi-unit residential buildings where battery banks of 100kWh or more are required, the Sunwoda's 32-unit scalability provides a clear path to 512kWh from a single battery model.

5. Integrated casters — the only battery with built-in wheels

The Sunwoda Atrix Max+ includes integrated casters as a standard feature. At 130 kg the battery is the heaviest of the three — heavier than the SAJ (110 kg) and Mesol (112 kg). Without casters, repositioning a 130 kg battery during installation or maintenance requires multiple people and equipment. The integrated casters allow a single person to roll the battery into position without lifting, a practical advantage that matters at the point of installation and any subsequent rearrangement.

16kWh Usable — What 100% DOD Actually Means

The Sunwoda Atrix Max+ datasheet claims 16kWh usable energy at 100% DOD under test conditions of 0.2C charge and discharge at 25°C. This requires context for Pakistani buyers.

What 100% DOD means: Depth of discharge refers to how much of the battery's total capacity is used before recharging. At 100% DOD the full 16kWh is accessible. The SAJ 16kWh recommends 95% DOD, giving 15.2kWh usable from the same 16kWh total.

The test condition caveat: The Sunwoda datasheet footnote states: "Test conditions: 100% DOD, 0.2C charge and discharge at 25°C." Real-world Pakistani conditions differ — summer ambient temperatures regularly exceed 35°C to 45°C, and discharge rates during load shedding with two ACs running are higher than the 0.2C test rate. At higher temperatures and discharge rates, usable capacity reduces slightly from the 16kWh rated figure.

Practical takeaway: The Sunwoda Atrix Max+ delivers more usable energy than the SAJ 16kWh in real conditions even after accounting for temperature differences. The 16kWh starting point at 100% DOD gives it a capacity advantage that persists across normal Pakistani operating conditions.

Who Is the Sunwoda Atrix Max+ For

Ideal for:

• Buyers prioritising maximum cycle life and long-term ROI over the lowest initial price
• Off-grid systems where deep daily cycling makes 10,000 cycle life financially significant
• Large systems requiring more than 16 batteries in parallel (up to 32 units)
• Properties where wall-mounted installation is preferred over floor-standing
• Installations where independent battery monitoring via integrated WiFi is required
• Buyers using non-SAJ inverters who need both CAN 2.0 and RS485 compatibility

Consider the SAJ 16kWh instead if:

• You own a SAJ H2 inverter and want plug-and-play CAN pairing
• Budget is the priority — the SAJ saves Rs 20,000 versus the Sunwoda
• Your installation requires outdoor or IP65-rated placement — SAJ is IP65, Sunwoda is IP20
• Your system will not exceed 16 batteries in parallel

Consider the Mesol 16kWh Infiniti instead if:

• Pakistan-specific local support is the deciding factor
• Your inverter requires RS485 only and CAN is not supported

Sunwoda Atrix Max+ vs SAJ 16kWh

Choose Sunwoda if: You want maximum cycle life, faster charging, larger parallel capacity, wall mount option, or integrated WiFi and the Rs 20,000 premium is acceptable.

Choose SAJ 16kWh if: You have a SAJ H2 inverter, need outdoor IP65 installation, or the Rs 20,000 saving is important.

---

Sunwoda Atrix Max+ vs Mesol 16kWh

The Sunwoda Atrix Max+ outperforms the Mesol 16kWh on every technical specification and costs Rs 35,000 less. The Mesol's advantage is Pakistan-specific brand positioning and local support network — a meaningful consideration for buyers who prioritise domestic support over raw specification performance.

Installation — Floor or Wall Mounted

The Sunwoda Atrix Max+ supports both floor-mounted and wall-mounted installation, with wall mounting listed as optional on the official datasheet. This is the only 16kWh LV battery at MartOnline with a wall-mount option.

Floor mounting: The standard configuration, standing on the floor with integrated casters for easy positioning. At 500mm wide, 970mm tall and 265mm deep, the Sunwoda is taller and deeper than the SAJ 16kWh (430 × 790 × 224 mm) but has a smaller footprint width. The integrated casters allow one person to move the 130 kg battery without mechanical assistance.

Wall mounting: An optional wall bracket allows the Sunwoda to be wall-mounted in locations where floor space is limited. For utility rooms with limited floor area, or for properties where the battery must be elevated for flood or water protection, the wall-mount option provides installation flexibility that neither the SAJ 16kWh nor the Mesol 16kWh can match.

Indoor only — IP20: The Sunwoda Atrix Max+ is rated IP20 and specified for indoor installation only. IP20 protects against solid objects larger than 12mm but offers no meaningful water or dust protection. For outdoor or exposed installation, the SAJ 16kWh with IP65 is the appropriate choice.

---

Integrated WiFi — Independent Battery Monitoring

The Sunwoda Atrix Max+ includes an integrated WiFi module as standard. This enables direct battery monitoring through Sunwoda's app without depending on the inverter's monitoring system.

For installations using non-Sunwoda inverters — GoodWe, SAJ, Crown Micro — the inverter monitoring app shows battery state of charge and basic data through CAN or RS485 communication. The Sunwoda's integrated WiFi additionally allows direct battery-level monitoring independent of the inverter, providing a second monitoring channel and enabling remote firmware updates to the battery BMS directly from Sunwoda.

---

Warranty and Certifications

The Sunwoda Atrix Max-16L-PK carries a 6-year manufacturer warranty, one year longer than the SAJ 16kWh's 5-year standard (the SAJ offers 10 years as an optional extension). Certifications confirmed on the official datasheet include IEC62619 (lithium battery safety), CE and UN38.3 (transport safety).

Frequently Asked Questions

What is the Sunwoda Atrix Max+ price in Pakistan?

The Sunwoda Atrix Max+ 16kWh battery (model Atrix Max-16L-PK) price in Pakistan is Rs 600,000 from MartOnline as of October 2026, including free delivery across Pakistan. This places it between the SAJ 16kWh at Rs 580,000 and the Mesol 16kWh at Rs 635,000. For the Rs 20,000 premium over the SAJ, the Sunwoda delivers 10,000 cycles versus 8,000, 16kWh usable versus 15.2kWh, and 11.2kW charge and discharge power versus the SAJ's 8kW charge limit.

How does the Sunwoda Atrix Max+ compare to the SAJ 16kWh?

The Sunwoda Atrix Max+ offers higher cycle life (10,000 vs 8,000+), more usable capacity (16kWh vs 15.2kWh), faster charging (11.2kW vs 8kW), double the parallel scalability (32 vs 16 units), integrated WiFi, integrated casters and a 6-year warranty versus 5 years on the SAJ. The SAJ 16kWh is Rs 20,000 cheaper, is rated IP65 for outdoor installation (the Sunwoda is IP20 indoor only), and offers plug-and-play CAN pairing with SAJ H2 inverters. For most buyers using non-SAJ inverters where outdoor installation is not needed, the Sunwoda delivers more performance per rupee over the long term.

What is the cycle life of the Sunwoda Atrix Max+?

The Sunwoda Atrix Max+ is rated for 10,000 cycles using safe LFP cells, as confirmed on the official Sunwoda Energy datasheet Atrix Max-16L-PK dated 20260514. Test conditions are 100% DOD, 0.2C charge and discharge at 25°C. At one full cycle per day — the typical Pakistani household pattern — 10,000 cycles represents approximately 27 years of daily use. This is the highest confirmed cycle life figure among 16kWh LV batteries available from MartOnline as of October 2026.

How many hours backup does the Sunwoda Atrix Max+ give for a 10 marla home?

A typical 10 marla home in Lahore or 200 gaz home in Karachi running two 1.5 ton inverter ACs alongside fans, lights and refrigerator draws approximately 5,500W simultaneously. With one Sunwoda Atrix Max+ at 16kWh usable capacity, backup duration at this load is approximately 2.9 hours. Two batteries in parallel providing 32kWh usable give approximately 5.8 hours at the same load — sufficient to cover the typical 4 to 8 hour daily load shedding in most Pakistani cities. For off-grid use, three to four batteries are recommended for a 10 marla home.

Can I connect the Sunwoda Atrix Max+ to a SAJ H2 inverter?

Yes. The Sunwoda Atrix Max+ communicates via CAN 2.0 and RS485, both of which are supported by SAJ H2 single phase inverters. It is compatible with the SAJ H2 6kW, 8kW, 10kW and 12kW models. Unlike the SAJ 16kWh which offers plug-and-play auto-detection with SAJ inverters, the Sunwoda may require manual battery parameter configuration in the SAJ inverter settings. Confirm configuration requirements with your installer before purchase.

Can I add more Sunwoda batteries to my system later?

Yes. Up to 32 Sunwoda Atrix Max+ units can be connected in parallel, providing a maximum combined storage of 512kWh. This is the highest parallel scalability of any 16kWh LV battery available from MartOnline — double the 16-unit maximum of the SAJ 16kWh and Mesol 16kWh. Starting with one or two batteries and adding more over time is straightforward. The integrated casters make repositioning existing batteries during expansion significantly easier than with fixed-base alternatives.
