Solar charger/inverter VT-HF48S220V-5KVA

off-gridhybridall-in-one

Introduction
The VOITA VT-HF48S220V-5KVA is a hybrid inverter/charger combining a pure sine-wave inverter, an integrated MPPT solar charger and an AC battery charger to deliver UPS-capable backup power from a compact unit. The front LCD provides configurable settings (battery charge current, AC/solar charger priority, input voltage thresholds) and simple button operation for on-site tuning.

Key features

• Pure sine wave inverter with cold-start and ability to run without battery
• Built-in MPPT solar controller (MPPT range 120–450Vdc; max PV Voc 500V)
• Configurable input voltage ranges and battery charging current via LCD
• Selectable AC/Solar charger priority and compatibility with mains or generator input
• Automatic restart on AC recovery and comprehensive protections (overload, over-temperature, short circuit)
• Communication: RS485, RS232; optional dry contact and parallel communication port on parallel models
