Off-Grid Solar Kit · 20,000W · 32.14kWh · 14,400W PV
Two 10kW inverters paralleled for 20,000W of 120/240V split-phase power, two IP65 PowerMax 314 outdoor batteries (32.14kWh) and thirty-two 450W bifacial N-type panels (14.4kW) with Z-brackets, breakers and cables.
The SGR-20K32P is sized for whole-house off-grid living where several large loads run at once - central air, a well pump, an electric range and a workshop. Two SPH10048P inverters run in parallel for 20,000W continuous on 120/240V split-phase, each with its own two MPPTs (22kW of PV capacity combined), 200A charging, generator input and Wi-Fi monitoring. Up to six inverters can be combined for 48kW.
Storage comes from two PowerMax 314 Outdoor batteries: 32.14kWh of LiFePO4 in IP65 cabinets that are UL1973 and UL9540A certified and CEC listed, with touch screens, Wi-Fi/Bluetooth monitoring and an 8,000-cycle rating. Because they are outdoor rated, the batteries can be installed beside the house rather than taking up indoor space. Add up to 14 more for 257kWh.
Thirty-two SGN-450-BDG5 bifacial N-type panels generate 14,400W - about 58kWh a day at four sun hours, more with rear-side gain - and ship with 32 sets of Z-brackets. Four 50 ft PV cable sets, a battery parallel cable, two 300A DC breakers, four 25A PV breakers and 2/0 AWG cables are included. Compare with the SGR-20K30E (server-rack SG48100P batteries) if you prefer indoor storage.

Two UL1741 SPH10048P inverters in parallel with 120/240V output, expandable to six units (48kW).
Two PowerMax 314 batteries - IP65, 8,000 cycles, UL1973 / UL9540A, CEC listed, 10-year warranty.
Thirty-two 450W dual-glass panels at 22.5% efficiency, 30-year performance warranty, Z-brackets included.
Each inverter accepts 11kW of solar, leaving room for more panels later.
Schedule charging and discharging windows and monitor everything through the Wi-Fi app.
Two 300A DC breakers, four PV breakers, battery parallel cable and 2/0 AWG cables included.
Estimates assume 85% usable energy and typical load ratings; actual runtime depends on your appliances, weather and settings.
Same inverters and panels; the 20K30E uses six SG48100P server-rack batteries (30.72kWh) in an indoor cabinet, the 20K32P uses two PowerMax outdoor cabinets (32.14kWh) with UL9540A certification.
Each inverter accepts 11,000W of PV, 22kW total, so about 16 more 450W panels can be added.
Not required, but both inverters have generator inputs for extended cloudy periods.
