Fronus X1-GENKi 6kW Single-Phase Off-Grid Inverter

Note: No grid export and no net metering. Verified on the Fronus product page: this model has no Grid-Tie Operation block and no feed-in voltage or frequency range, so it cannot synchronise to WAPDA or K-Electric. It will still take utility or generator in as a backup source and charge the battery from it - that is not the same as being grid-interactive. Runs as an off-grid system: this unit runs the load from PV and battery and accepts grid or generator as a backup source, but it does not export to the grid, so it cannot be net-metered. Standard 48 V bank (40-60 V), lithium or lead-acid, 120 A charge and discharge - it works with the batteries already common in Pakistan. PV array ceiling is 12,000 Wp but maximum PV input power is 9,000 W, so the array can be substantially oversized against the tracker. EPS output 6000 VA with 12,000 VA peak for 10 s and switchover under 4 ms - the fastest transfer of any Fronus unit here. 17.3 kg, IP65, smart cooling, under 45 dB. 5-year warranty.
