Core electrical specs
Rated power: 7.5 kVA / 6 000 W, single‑phase, nominal DC input 48 V.
AC input: nominal 220 V AC, wide input range 90–280 V AC with automatic transfer between grid and inverter.
Efficiency: line‑mode efficiency ≥ 95% at rated load with fully charged batteries; transfer time AC↔DC typically 15 ms.
Output waveform: pure sine wave output in inverter mode; “same as input” in bypass/line mode.
Charging and battery
Max charging current: up to 60 A from AC in utility charge mode (some Li versions integrate BMS communication).
Adjustable charge current: settings like 0 / 10 / 20 / 30 / 40 A allow tuning to battery size and grid limits.
Battery protection: over‑charge protection, low‑battery alarm, low‑battery cut‑off and recovery points for 12/24/48 V systems (used here at 48 V).
Features and ideal use
Non‑hybrid / off‑grid focus: main job is to act as inverter‑charger with bypass charging and priority selection between grid and battery; connects to external Felicity MPPT for solar.
Protections: overload, short‑circuit, over‑temperature, AC input/output over‑current, reverse polarity and temperature‑compensated charging to protect batteries.
Typical applications: whole‑home backup or small business, running fridges, TVs, lights, computers and moderate motor loads from a 48 V battery bank with grid support and optional external PV.
