Performance
With 6,000W continuous output and up to 18,000W surge, the Hysolis SPS6K can easily run large appliances like refrigerators, air conditioners, power tools, or even a well pump. Its 240V split-phase output also makes it suitable for homes and workshops with higher voltage needs.
- Runs entire off-grid homes or backup loads
- Surge capacity handles motor startup and heavy-duty tools
- Can power 240V equipment (rare for solar generators)
Battery & Specs
The system comes standard with a 10.65kWh LiFePO4 battery, known for stability, long cycle life (3,500+ cycles), and safety. If your needs grow, Hysolis offers optional external battery packs to expand the total capacity up to 42.6kWh, providing multi-day autonomy.
- Battery chemistry: LiFePO4 (safe, long-lasting)
- Integrated BMS for battery protection
- Expandable up to 3 additional battery packs
Portability & Design
At over 200 pounds, the SPS6K is not meant for camping or quick transport. It’s designed to be a stationary power system, ideally installed in a garage, shed, or utility room. Heavy-duty wheels and handles help with placement, but this is a set-it-and-forget-it unit.
- Dimensions: 28.5″ x 19″ x 18″
- Steel-reinforced casing for durability
- Built-in display screen for power monitoring
Charging Options
Charging flexibility is where the SPS6K shines. You can recharge the battery via:
- Solar Input: Up to 4,400W via MPPT (charges in ~2.5 hours with max solar)
- AC Wall Charging: Standard 1,500W (slower, overnight charging)
- Gas Generator Input: Use as a fallback in bad weather
MPPT solar input means high efficiency and better performance in partial sunlight.
Price & Value
At around $6,000 – $7,000 depending on configuration and batteries, the SPS6K isn’t cheap — but for what it offers, it’s one of the best values in the high-output solar generator market.
- Cheaper than comparable all-in-one 240V units
- Modular battery expansion reduces initial investment
- No proprietary software lock-in or cloud dependencies
Ideal Use Cases
The Hysolis SPS6K is built for serious power needs. It’s ideal for:
- Off-grid homes or cabins
- Backup power for entire households
- Small farms, workshops, or job sites
- Solar system owners looking for whole-home storage
- Preppers and remote homesteads
Pros and Cons
Pros:
- Massive 6,000W inverter with 240V output
- Large 10.5kWh LiFePO4 battery standard
- Expandable up to 42.6kWh
- High solar input (4,400W max)
- Durable and no-nonsense build quality
- Lower cost per kWh than many competitors
