With 1024Wh of lithium iron phosphate (LiFePO4) capacity and a 1800W pure sine wave inverter (2500W surge), it powers everything from drill chargers and angle grinders to small inverters and lighting rigs. The standout feature is X-Stream fast charging - the unit reaches 80% in just 50 minutes on AC, and accepts up to 1100W of solar input for rapid recharge in direct sunlight.
For solar installers, the Delta 2 strikes the ideal balance between capacity and portability. At 27 lbs, it is heavy enough to be stable on a work surface but light enough for one person to carry up a ladder. The multiple output options - 4 AC outlets, 2 USB-C ports (100W max), 1 USB-A port, and a 12V car socket - mean a crew can charge drills, multimeters, and phones simultaneously.
The LiFePO4 battery chemistry provides 3,000+ cycles to 80% capacity, meaning years of daily job site use without significant degradation. The built-in app connectivity lets users monitor charge status, adjust output settings, and schedule charging windows remotely - useful when the unit is placed on a roof while the crew works below.
The Bluetti AC200MAX is the heavy-duty choice for solar crews that need maximum power capacity. With 2,048Wh of LiFePO4 storage and a 2,000W continuous inverter (4,800W surge), it can run tools that demand more power than most compact units can handle - including 7-amp angle grinders, hammer drills, and small welders.
The 4 AC outlets, 2 USB-C ports (140W), 1 USB-A port, and 12V car socket provide versatile charging for an entire crew. The unit supports up to 1,400W solar input, which means it can recharge from a pair of 200W panels in about 1.5-2 hours of good sunlight - a game-changer for all-day job sites without grid access.
At 66 lbs, the AC200MAX is not a one-person carry, but the built-in handle and optional wheel kit make it manageable on flat surfaces. The robust construction and IP65-rated enclosure mean it can withstand dust, rain, and job site abuse.
The Jackery Explorer 500 Pro is the best compact portable solar generator for solar installers who need portability without sacrificing performance. At just 18.7 lbs with a built-in handle, it is light enough to carry up a ladder or stash in a tool bag.
With 518Wh of capacity and a 500W pure sine wave inverter (1000W surge), it handles drill chargers, LED work lights, multimeters, and small power tools - the workhorses of a solar installation crew. The 3 AC outlets, 2 USB-C ports, and 1 USB-A port cover most charging needs for a single installer.
Solar recharge is straightforward with a 300W max input - pair Jackery solar panels and you have a complete off-grid power system. The rugged, compact form factor and 10-year lifespan make it a solid investment for solo operators.
The Goal Zero Yeti 500X delivers reliable power at a competitive price point, making it the best value portable solar generator for budget-conscious solar installers. With 505Wh of lithium battery capacity and a 500W pure sine wave inverter (1000W surge), it covers the same tool-charging needs as more expensive units.
Goal Zero is known for build quality and customer support, and the Yeti 500X carries that reputation. The unit accepts up to 200W solar input and can also charge via AC or vehicle outlet. The integrated LED light strip is a handy feature for working in dark attics or crawl spaces during installation.
At 21 lbs, it is slightly heavier than the Jackery 500 Pro but still manageable for one person. The expandable design lets you add Goal Zero Yeti Battery expansions later if your power needs grow.
The EcoFlow River 2 Pro is the best modular portable solar generator for crews who want to start small and scale up. With 768Wh of LiFePO4 capacity in a compact 17-lb package, it powers tools and chargers for a single installer, and additional River modules can be stacked to increase capacity as your business grows.
The standout feature is the modular expandability - you can connect up to two additional River 2 Pro units for 2,304Wh total capacity. The X-Stream fast charging (80% in 50 min) and 500W solar input keep the system ready between job sites.
At 17 lbs, this is the lightest option in the comparison - ideal for installers who carry power up ladders daily. The 768W pure sine wave inverter handles drill chargers, LED lights, and small tools with room to spare.
