Inverters
Every inverter we sell, grouped by what it does. Grid-tie inverters send solar to the house and the surplus to the utility, with no battery. Hybrid inverters do that and charge a battery, and keep running in an outage. Off-grid inverters run a building from a battery bank with no utility at all. Pure sine wave inverters turn a 12 V or 24 V battery into 120 V AC for an RV, boat or cabin.

Growatt MIN TL-XH-US, 3.8 kW to 11.4 kW, are the grid-tie inverters our kits use and are battery-ready for backup later. The Growatt 10 kW split-phase hybrid and SPH series add storage and a UPS-grade changeover. The SPE 6000 and 12000 and the 3.5 kW single-phase unit are off-grid, split-phase 120/240 V or 120 V. ROCKSOLAR 2,000 W and 3,000 W pure sine wave inverters cover mobile and small cabin use. For three-phase commercial buildings see the Growatt WIT.
Size an inverter to the largest load you will run at once, with headroom for motor starts, and check its PV input against your array. The finder above will match one to your loads, or send us your panel schedule.
