Description
Sungold Power | Off-Grid Solar Kit | 8000W 48VDC 120V/240V LiFePO4 | 10.24KWH Lithium Battery | 8 X 450W Bifacial Solar Panels | SGR-8K10E / SGR-8K10T
Most off-grid kits make you choose between running 240V equipment and running it comfortably. This is the point in the range where that stops being a trade: 8,000W of continuous split-phase output with 16,000W of peak behind it, so a well pump can start while the shop tools are already running. It’s built for a full-time off-grid house, a working farm, or a property where the 240V side isn’t occasional. 3,600W of bifacial panels generate 14 to 18kWh on a normal day, against the 8.7kWh the battery delivers overnight.
Two battery configurations, one decision. Both hold 10.24kWh and everything else is identical. The SGR-8K10E splits it across two 93 lb server-rack units; the SGR-8K10T is one 198 lb wall or floor mounted unit. The section below is the whole difference.
Key features
8,000W continuous with 16,000W of peak – Double the rated output on tap for starting motors. On a working property that’s what lets a well pump kick in without dimming the shop, and it’s the main reason to be at 8kW rather than 6.5kW.
UL1741 listed by ETL – A recognised safety listing, which is usually the first thing a building department or an insurer asks about. Most off-grid inverters at this size carry nothing comparable.
Bifacial N-type panels, 22.5% efficient – Dual-glass modules that generate from the back face as well as the front, at up to 80% of front-side output where light reflects onto them. Over gravel, concrete, a light roof or snow that’s real extra production the 450W nameplate doesn’t capture. N-type cells also avoid the light-induced degradation that affects conventional P-type panels, and carry a 30 year linear performance warranty rather than the usual 25.
Room for three times the array – Two independent MPPT trackers and 11,000W of PV capacity against the 3,600W included. The kit uses one tracker, so the second is sitting free for a second string.
Six units in parallel – Up to 48,000W of output if the property outgrows one inverter, without replacing what you already bought.
Your choice of battery format – Two server-rack units or one large wall-mounted unit, same 10.24kWh either way. The configuration table above is the whole decision.
