Off-Grid Solar Kit · 24,000W · 61.44kWh · 18,290W PV
A large-home off-grid power plant: two FR12K-B inverters paralleled for 24,000W of 120/240V split-phase output, twelve CoreX 5 Pro server-rack batteries totalling 61.44kWh, and thirty-one 590W bifacial N-type panels producing 18.29kW.
The FR-24K60CP is Sungold Power's largest FR-series kit, sized for big remote homes, ranches and multi-building properties that need full-time off-grid power with well pumps, central air, electric ranges and workshop tools running at the same time. Two FR12K-B inverters share the load in parallel for 24,000W continuous and 48,000W of surge, on 120/240V split-phase.
Twelve CoreX 5 Pro batteries - 100Ah 51.2V LiFePO4 modules built on EVE Grade A cells with a 100A smart BMS each - provide 61.44kWh of storage, enough to carry a 25-30kWh/day household for two days without sun. Thirty-one SGN-590-BDG1 bifacial N-type panels deliver 18,290W of PV, about 73kWh a day at four sun hours, recharging the bank quickly even in winter.
Each inverter has two MPPTs (13.2kW PV capacity per unit, 26.4kW total), a generator input with auto-start support, built-in PV rapid shutdown and breakers, and Wi-Fi monitoring. The kit includes battery brackets, four 50 ft 10 AWG PV extension cables, two 4/0 AWG battery cables and four 25A PV breakers. A PowerMax outdoor-battery version (FR-24K64PM) is also available.

Two FR12K-B inverters in parallel: 24,000W continuous, 48,000W peak, 120/240V, 6HP motor capability per unit.
Twelve CoreX 5 Pro 5.12kWh rack batteries with EVE Grade A cells, 6,000+ cycles, CAN/RS485 closed-loop and Bluetooth/Wi-Fi monitoring.
Thirty-one 22.8% efficient N-type dual-glass modules with 30-year performance warranty.
Both inverters accept generator input (90-140Vac) with auto generator start for extended cloudy periods.
Rapid shutdown and AC/DC breakers inside each inverter for code compliance and safer installation.
Add up to four more inverters (72kW total), three more batteries per stack (15 max) and 8kW more PV.
Estimates assume 85% usable energy and typical load ratings; actual runtime depends on your appliances, weather and settings.
Battery mounting brackets for the twelve CoreX 5 Pro modules are included; a server-rack cabinet is optional.
About 73kWh at four full sun hours from the 18.29kW array, plus bifacial gain - enough to run most large homes and recharge the 61.44kWh bank in a day.
The FR12K-B is an off-grid inverter/charger: it can use grid or generator power as a charging and pass-through source but does not export to the grid.
