SolarMax Solon Dual 3.8kW Off-Grid Inverter Price in Pakistan

Note: 3800 W on a 24 V battery bank from up to 5000 W of PV, with a 60 to 450 V MPPT window on a 500 V open-circuit ceiling and 27 A of PV input current. 120 A of solar charging against 100 A from the grid. Surge 7600 VA. Dual AC output, a main load and a smart load, so non-critical circuits can be shed separately. Output 230 V with a selectable 170 to 280 V window for computers or 90 to 280 V for appliances, switching in 10 ms or 20 ms. It runs without a battery, and the low-voltage cut-off is selectable from 21 to 24 V with the high-voltage point selectable from 25 to 30 V, which is more control than this class usually gives. The display shows state of charge as a percentage as well as voltage. Built-in WiFi and RS485 for a lithium BMS. No grid export and no net metering: the datasheet has no grid-output or feed-in section. It runs the load from PV and battery and takes utility as a backup charging source, which is not the same as being grid-interactive. The 98% on the sheet is the MPPT charger's own efficiency, printed inside the solar charger block, not a PV-to-AC conversion figure, so the efficiency field is left empty rather than filled with a number that measures something else. Rated 5% to 90% humidity and -10 to 50 °C. The sheet gives no IP rating, no warranty term, no protection list and no MPPT tracker count, so those fields are left empty rather than guessed. 8.84 kg, and the case is 340 mm wide, 420 mm tall and 125 mm deep; the sheet labels that row D x W x H. Against the Solon 3kW: 800 W more output, 1000 W more PV, 27 A instead of 18 A of PV input current, 120 A instead of 80 A of charging, a second AC output, and it tolerates -10 °C where the 3kW stops at 0 °C. Price shown is the w11stop.com listing, Rs 75,000 (in stock), read 24 September 2026.
