Off-Grid Solar Kit · 10,000W · 32.14kWh · 6,600W PV
10kW Off-Grid Solar Kit with 32.14kWh of PowerMax Outdoor Storage
A 10kW 120/240V split-phase off-grid kit with two weatherproof PowerMax 314 outdoor batteries (32.14kWh), twelve 550W monocrystalline panels with Z-brackets, breakers and cables – storage that can live outside the house.
SGR-10K32P Overview
The SGR-10K32P is the PowerMax version of Sungold Power’s popular 10kW off-grid kit: instead of a rack of server batteries indoors, two PowerMax 314 Outdoor cabinets (IP65, UL1973 and UL9540A certified, CEC listed) hold 32.14kWh of LiFePO4 storage and can be installed on a pad outside, in a garage or a shed. Each has a touch screen, Wi-Fi/Bluetooth monitoring and an 8,000-cycle rating.
The SPH10048P inverter delivers 10,000W of pure sine wave power at 120/240V split-phase (or 120V single-phase), charges at up to 200A, accepts 11,000W of solar on two MPPTs and is UL1741 listed by ETL. It supports time-slot charging and discharging, Wi-Fi app monitoring and closed-loop communication with SunGoldPower batteries; up to six units parallel for 48kW in single-, split- or three-phase.
Twelve SG550WM monocrystalline panels supply 6,600W – about 26kWh a day at four sun hours – and ship with twelve sets of Z-brackets for roof mounting. Two 50 ft PV extension cable sets, a battery parallel cable, a 300A DC breaker, two 25A PV breakers and 2/0 AWG cabling complete the kit.

SGR-10K32P Common Questions
Can the batteries be installed outdoors?
Yes. PowerMax 314 Outdoor batteries are IP65 rated for indoor or outdoor installation and operate from 14°F to 131°F.
How is this different from SGR-10K25S?
SGR-10K25S uses five SG48100P server-rack batteries (25.6kWh) in an indoor cabinet; SGR-10K32P uses two PowerMax outdoor cabinets with 32.14kWh and UL9540A certification.
Can I add more solar?
Yes – the inverter accepts up to 11,000W of PV, so roughly eight more 550W panels can be added.
Does the kit ship free?
Yes – free shipping within the contiguous USA (freight delivery for kits), $0 sales tax in most states.
