An 8kW solar power system supports a large home or busy shop with comfortable margin. Three Sungold Power options are in stock from $5,518, all 48VDC off-grid kits with 120/240V output and LiFePO4 storage. Their split-phase output runs both standard outlets and 240V loads like pumps and dryers. The main decision is how much battery you want alongside the 8,000W inverter, since capacity sets overnight runtime. Review the included panels and battery sizes in each listing, then call or email for help sizing against your electric bill.

An 8kW solar system is the step where 240V arrives. Every kit here is built around an 8,000W 48V inverter with 120V/240V split-phase output, which is what a well pump, an electric dryer, a central air handler or a 240V workshop tool needs. Paired with 10 to 20kWh of LiFePO4 storage and a 3,300W to 5,400W array, these packages are sized for a full-time off-grid house or a home that wants to ride out multi-day outages.
The collection holds four Sungold Power packages. The 8kw solar system price runs from $5,518 for the SGR-8K10E with 10.24kWh and eight 415W panels, through $6,979 for the SGK-8MAX with a 5,400W array, to $8,880 for the SGM-8K20 with 20.48kWh of battery. A fourth option, the 14.3kWh Complete 48V Power System without panels, is sold out at $5,899.
Not sure 8kW is the right size? Our guide what size solar system do I need turns your monthly kWh into array kW and panel count, and explains why a kit's 8,000W inverter rating is not the same as its panel wattage.
| Product | Key numbers | Best for | Price from |
|---|---|---|---|
| Sungold Power SGR-8K10E | 8,000W, 10.24kWh, 8 x 415W (3,320W) | Mid-size home, sunny region | $5,518 |
| Sungold Power SGK-8MAX | 8,000W, 10.24kWh, 12 x 450W (5,400W) | Short winter days, faster recharge | $6,979 |
| Sungold Power SGM-8K20 | 8,000W, 20.48kWh, 12 x 415W (4,980W) | Full-time off-grid with heavy nightly use | $8,880 |
Is an 8kW solar system kit enough to go fully off grid? For a modest home with propane or wood heat and a gas range, yes. The SGM-8K20's 20.48kWh and 4,980W array cover a typical family's daily use with reserve; homes with electric heat need more storage and array than any single kit here.
What is the difference between the SGR-8K10E and SGK-8MAX? Same 8,000W inverter class and 10.24kWh of battery; the 8MAX adds four more panels and steps each up to 450W for 5,400W total, plus a Bluetooth-enabled battery. The $1,461 difference buys roughly 60% more solar.
Can I run a 240V well pump? Yes. Split-phase 120V/240V output is standard on every kit in this collection, unlike the 120V-only 5kW packages.
Kits ship free to the mainland US from Sungold Power's partner warehouse, usually within a few business days, with 30-day returns. Call us with your load list and we will confirm which 8kW package matches it.
