Buyer-focused FAQ

Q: Will it keep my home powered during long outages?
A: Yes! 6,500W output + 13,000VA surge handles heavy loads, and 1–6 unit parallel support scales for whole-home backup.

Q: How fast can it recharge my batteries after a blackout?
A: Industry-leading 140A hybrid charging — refills batteries 70% faster than standard inverters using grid + solar combined.

Q: Will my solar panels waste energy when batteries are full?
A: No! Dual 5,000W MPPTs capture more sun, and 140A charging converts excess solar to battery power instantly.

Q: Is it compatible with my existing battery/solar setup?
A: Yes. Works with any battery (Li-ion/lead-acid/custom), high-voltage PV strings (550V), and unstable grids (65–140V).
