Boosts PV energy 10-20% without increasing PV array size and reduces storage inverter costs up to 30%
Improve battery efficiency by 10-15%; Partial Charge Carbon AGM’s round trip efficiency is 98% vs. wet cell 80%
Sol-Ark 12K’s All-In-One design cuts install time in half. With 2x MPPTs, and 9kW continuous / 20kW peak inverter, a user friendly wiring area, and remote monitoring built in. We also guide you 7 days a week via our engineering support. Call us!
Sol-Ark 12K supports simultaneous DC and AC coupling up to a combined 16.5kW of PV.
Sol-Ark 12K acts as a massive uninterruptible power supply with a lightning fast 4ms transfer time.
3X Better! Only 3.5% losses vs. 14% in today’s battery based systems
Sol-Ark’s 12K pumps out power just like the grid, allowing you to power 120V/ 240V/208V appliances
Manages power from Solar, Battery, Grid, Load, and Generator simultaneously
Sol-Ark is expandable from 5 to 52 (16.5 kW) solar panels and 0-32 batteries. Per 12K unit.
No need for additional warranties. The 12K comes standard 10-year warranty right out of the box.
Parallel Stacking, Grid Sell, Meter Zero, Time of Use, Smart Load, AC Coupling, Peak Shaving, 20 kW Peak Power
Proven to last well beyond the standard 10 year warranty
