Keep the unit away from rain, water, and extreme temperatures (humid or flammable environments) to prevent malfunctions—critical for both Home Backup Power and Camping Portable Power Station applications.
Solar Charging Compatibility:
As a dedicated Solar Generator, only use 18V-80V solar panels (maximum 2500W for 3KW models, 3000W for 5KW models) to avoid damaging internal components.
2.Home Backup Readiness:
For reliable Emergency Power Supply performance, maintain the battery at 50%-70% charge when not in use and store it in a dry, well-ventilated area with temperatures between 15℃-25℃.
3.Load Management:
Do not exceed the rated AC output (3000W for 3KW models, 5000W for 5KW models). Overloading will activate the protection mechanism, potentially causing power interruptions during critical use in RV or home backup scenarios.
Yes. The 3KW model powers small to medium appliances (fridges, microwaves, LED lights) simultaneously, while the 5KW model handles larger loads (mini air conditioners, washing machines). Check your appliance’s power rating to ensure it doesn’t exceed the unit’s rated output (3000W/5000W).
No—any 18V-80V solar panel (monocrystalline/polycrystalline) works. The 3KW model supports up to 2500W panels, and the 5KW model up to 3000W. For best results, use panels with matching voltage to maximize the MPPT controller’s efficiency.
The LiFePO₄ battery offers over 2000 charge-discharge cycles (to 80% capacity). With regular use (1-2 cycles/week), it can last 8-10 years—much longer than standard lithium-ion batteries.
Absolutely. LiFePO₄ batteries are non-toxic and resistant to thermal runaway, and the built-in overheat/short-circuit protection ensures safety. Keep it in a well-ventilated area (avoid closed cabinets) during high-load use.
Yes. The QH-033 supports dual charging (AC + solar), which shortens the full charge time. For example, the 3KW model can fully charge in 1.5-2 hours with both AC and 2500W solar input.
Most shutdowns are triggered by protection mechanisms (overload, overheat, low voltage). Check:
Yes. It’s designed as a dedicated RV Portable Power solution—connect via the 12V DC ports (for RV accessories) or AC 220V output (for larger RV appliances). Its compact size fits easily in RV storage compartments.
