A portable solar generator has three main components: solar panels that capture sunlight and convert it to DC electricity via photovoltaic cells; a lithium battery (usually LFP or NMC) that stores that electricity; and an AC inverter that converts the stored DC power into the AC power your appliances need. You can charge the battery from solar panels, a wall outlet, a car's 12V port, or any combination simultaneously.

Start by adding up the wattage of every device you want to run simultaneously, then add 20-30% as a safety margin for power surges. For reference: a mini-fridge draws ~100W, a full-size fridge ~150-200W, a CPAP ~30-80W, and a window AC ~1000-1500W. Multiply the total wattage by the hours you need to run the devices to get your required watt-hours (Wh). A 1000Wh generator running a 100W fridge gives you ~10 hours of runtime.

LFP (Lithium Iron Phosphate) batteries are safer, have longer cycle lives (2,000-6,500+ cycles), don't overheat or catch fire as easily, and are the preferred chemistry for home backup and heavy use. NMC (Nickel Manganese Cobalt) batteries have higher energy density (more power in less space/weight) but shorter cycle lives and slightly more thermal risk. For home backup, we recommend LFP -- EcoFlow's DELTA Pro, Mango Power E, and most Lion Energy units use LFP chemistry.

For essential circuits (fridge, lights, router, phone charging, CPAP), a 3-5kWh unit like the Mango Power E or EcoFlow DELTA Pro is a strong starting point. For 240V appliances (dryers, well pumps, central HVAC), you'll need a dual-unit setup like the Mango Power E + mSocket Pro. For a complete whole-home backup system integrated into your electrical panel, the EcoFlow Smart Home Panel or Mango Power mPanel Pro can automate the switchover. Call us and we'll help you design the right system.

Solar generators are silent, produce zero emissions (safe indoors), require no fuel, need virtually no maintenance, and can be recharged for free using sunlight. Gas generators are louder, emit carbon monoxide, require ongoing fuel purchases, need regular oil changes, and cannot be operated inside. Over a 10-year period, a household can save approximately $15,000 in fuel costs by switching from a diesel generator to solar. The main trade-off is upfront cost and the limitation that solar generators cannot yet match the raw output of large industrial gas generators.

Yes -- all generators we carry support outdoor and RV use. Most include a 12V car charging input and many include a 30A RV outlet (like the Mango Power E). For camping, a portable solar panel paired with a 500-1000Wh unit is ideal for phones, laptops, lights, and a small fridge. For full-time RV living, a 2-4kWh unit with roof-mounted or portable solar panels provides genuine energy independence between campsite hookups.
