Off-Grid Solar Kit · 24,000W · 61.44kWh · 18,290W PV
24kW Off-Grid Solar System with 61.44kWh of CoreX 5 Pro Storage
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.
FR-24K60CP Overview
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.

FR-24K60CP Common Questions
Is a battery rack included?
Battery mounting brackets for the twelve CoreX 5 Pro modules are included; a server-rack cabinet is optional.
How much power can the kit produce per day?
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.
Can I connect it to the grid?
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.
Does the kit ship free?
Yes – free shipping within the contiguous USA (freight delivery for kits), $0 sales tax in most states.
