Core electrical specs
Rated output: 2 500 VA / 2 000 W, single‑phase 220 V AC from a 12 V DC battery bank.
AC input: 220 V AC nominal with a wide 90–280 V AC range, automatic transfer, and pass‑through without battery support.
Efficiency: line‑mode efficiency ≥ 95% at rated load with fully charged batteries.
Waveform & surge: pure sine‑wave output in inverter mode; surge rating 2 × rated power for 5 seconds, capable of starting motor loads like fridges or pumps.
Charging and battery protection
Charger: built‑in AC charger up to 40 A, with adjustable charge current (0, 10, 20, 30, 40 A) to match battery size and grid capacity.
Battery: 12 V bank, with multi‑stage charging and protection for over‑charge, low‑battery alarm, low‑battery shut‑down, high DC input alarm and recovery.
Features and best use
Role: transformer‑based inverter‑charger; solar is added via a separate MPPT/PWM controller, but the IVPS can communicate with Felicity MPPTs in Li variants.
Extras: grid/battery priority selection, RS‑232 communication, intelligent protections and robust design for continuous off‑grid or backup use.
Ideal applications: small homes, shops or offices needing reliable 12 V backup for lights, TV, Wi‑Fi, fans and other light‑to‑medium loads.
