Core electrical specs
Rated output: 3 500 VA / 2 800 W, single‑phase 220 V AC pure sine‑wave from a 24 V DC battery bank.
AC input: nominal 220 V AC, wide input range 90–280 V AC with automatic transfer between grid and inverter; transfer time AC↔DC typically 15 ms.
Efficiency: line‑mode efficiency ≥ 95% at rated load with fully charged batteries.
Waveform: pure sine wave in inverter mode; in line/bypass mode the output waveform follows the AC input.
Charging and protections
AC charger: max utility charge current 40 A, adjustable 0–40 A to match battery bank and grid capacity.
Battery protection: over‑charge protection, low‑battery alarm and cut‑off, high‑DC alarm/cut‑off, plus built‑in battery reverse‑polarity protection.
Features and ideal use
Role: inverter‑charger with bypass charging (AC charging available even when unit is off); solar is handled by an external MPPT or PWM controller.
Extras: RS232 communication, LCD/LED display, generator auto on/off support, battery temperature‑compensation interface and selectable battery types via three‑stage smart charger.
Applications: small‑to‑medium home or office systems needing a 24 V, 2.8 kW pure sine‑wave backbone for lights, electronics and fridges, with grid/generator plus external solar charging
