Description
SunGold Power | Off-Grid Solar Kit | 20KW 48VDC 120V/240V | LiFePO4 32.14KWH Outdoor Battery | 32 X 450 Watt Bifacial Solar Panels | SGR-20K32P
Two 10,000W inverters, thirty-two bifacial panels and 32.14kWh of storage in two sealed batteries that live outside. Nothing in this system needs a conditioned room. The array makes 58 to 72kWh on a good day, the bank delivers 27.4kWh to your outlets on a bad one, and a refrigerator runs 182 hours on storage alone.
One limit to know before you buy, because it is the reason this kit exists in two versions. Each PowerMax battery sustains 150A, which is 7.68kW. Two of them supply 15.36kW of DC, and after the inverters convert it that is roughly 14,100W at the outlet, not the 20,000W the inverter pair is rated for. Surge is unaffected: starting a well pump, a compressor or an air conditioner draws hard for a second or two and both the inverters and the batteries handle it. What the ceiling limits is sustained load. If you need to hold more than 14,000W for long stretches, the SGR-20K30E puts six server-rack batteries behind the same two inverters and removes it. If you need the batteries outdoors, this is the kit, and 14,000W sustained is more than most properties ever hold.
Key features
Batteries rated to live outside – Two PowerMax 314 units, IP65 sealed, wall or floor mounted, 271 lbs each. Every other battery format we pair with a kit this size needs an indoor space and usually an enclosed cabinet to sit in.
20,000W from two paralleled inverters – Two 10,000W units working as one, with 40,000W of combined surge. Two inverters also means a fault takes half the system offline rather than all of it, which is not true of any single-inverter kit.
14,400W of bifacial N-type solar – Thirty-two dual-glass modules generating from the rear face as well as the front. N-type cells avoid the light-induced degradation of conventional P-type panels and carry a 30 year linear performance warranty.
Four independent MPPT trackers – Two per inverter, which is why the kit ships four PV breakers and four sets of extension cable. Four trackers means up to four roof planes or ground-mount orientations without one shaded string dragging down the others.
8,000 cycles at 80% depth of discharge – At one cycle a day that is past twenty years, and the batteries carry a 10 year warranty against a 3 year warranty on the inverters.
UL1741 listed by ETL – A recognised safety listing on both inverters, and usually the first thing a building department or an insurer asks about. The batteries carry UL1973 and UL9540A.
Expandable on both sides – Up to six inverters for 60,000W of output, and up to sixteen PowerMax units in parallel. Adding a third and fourth battery is also what lifts the sustained ceiling described above.
