Frequently Asked Questions
- The Auxsol ASG-12TL-ZL 12kW at Rs 440,000 versus GoodWe GW12K-ET-L at Rs 485,000 and Inverex Nitrox 12kW at Rs 750,000. Output: all three at 12kW. Charging current: Auxsol leads at 250A versus GoodWe at 228A and Inverex at 240A. Solar input: Auxsol at 24kW matches GoodWe at 24kW and exceeds Inverex at 15.6kW. MPPT: GoodWe leads at 3 MPPTs versus Auxsol and Inverex at 2. Backup switching: Auxsol under 4ms matches GoodWe under 4ms and beats Inverex at 4ms. Price: Auxsol is Rs 45,000 cheaper than GoodWe and Rs 310,000 cheaper than Inverex. Automatic generator control and I-V curve scanning are unique to Auxsol at this price. For buyers prioritising value, Auxsol 12kW three phase offers the best specs-to-price ratio in Pakistan.
- The Auxsol ASG-12TL-ZL 12kW is suited for offices above 3000 square feet, small factories, schools, clinics, commercial shops and medium hotels with three-phase connections in Pakistan. For a 5000 square foot office in Karachi or Lahore with 3-4 split ACs, computers, lighting and server loads totalling 8-10kW, the Auxsol 12kW provides comfortable headroom and reliable backup. The automatic diesel generator control is particularly valuable for commercial premises where extended outages require generator backup without manual intervention. Paired with a 16kWh lithium battery, it provides 4-5 hours of full commercial backup.
- The Auxsol ASG-12TL-ZL 12kW has a 250A maximum battery charging current — the highest of any 12kW three-phase LV hybrid inverter available in Pakistan, exceeding GoodWe GW12K-ET-L at 228A and Inverex Nitrox 12kW at 240A. For a 48V 16kWh battery (333Ah), 250A charging means the battery recharges from empty to full in approximately 1.3 hours at maximum rate. In Pakistani commercial conditions where load-shedding can occur multiple times per day, faster battery recharging ensures the battery is always ready for the next outage. This 250A charging rate is particularly valuable for commercial premises with solar systems operating in partial shade or during overcast periods when charging power is reduced.
- Yes, the Auxsol ASG-12TL-ZL 12kW supports grid-connected operation and grid-connected AC coupled access, making it compatible with NEPRA net metering requirements for commercial electricity consumers in Pakistan. It can export surplus solar energy to the grid during periods when solar generation exceeds building consumption, earning net metering credits against the monthly electricity bill. For a commercial office with 24kWp of solar panels and the Auxsol 12kW, net metering can reduce the monthly electricity bill by Rs 50,000-100,000 depending on consumption patterns and DISCO net metering tariff rates.
- For the Auxsol ASG-12TL-ZL 12kW in a commercial premises, a minimum of 16kWh of lithium storage is recommended for 4-5 hours of backup. For 8 hours of commercial backup covering a full working day, 32kWh (2 x 16kWh batteries) is recommended. Compatible batteries at MartOnline include Sunwoda Atrix Max 16kWh (Rs 600,000), Pylontech Fidus Plus 16kWh (Rs 625,000) and Crown 16kWh (Rs 630,000). The 250A charging current means a 16kWh battery recharges in approximately 1.5 hours of full solar generation — ideal for commercial premises where batteries need to recharge quickly between load-shedding periods.
