The Sol-Ark Essentials 12K (12K-2P-N) is a cost-effective all-in-one hybrid inverter for partial-home backup. It provides 9kW of continuous output with a 16kVA surge, enough to start small well pumps, compressors and other motor loads. It supports DC- and AC-coupled solar, transfers to backup in 4ms, and has a 63A grid passthrough, Smart Load output and GEN port, so it doesn't need extra PCS hardware.
Highlights
- 9kW continuous, 16kVA 10 s surge (25kVA for 100ms)
- 2 MPPTs, 13kW max PV, 500V max input
- 4ms transfer; 63A grid passthrough
- Stack up to 9 in parallel
- Integrated protection: PV disconnect, rapid shutdown, arc-fault and ground-fault detection, 250A battery breaker, 63A AC breaker
- Wi-Fi and LAN monitoring hardware included; 10-year warranty
