3kW UPS System — 4.8 kWh Energy Storage | 4Boats

Compact 3 kW uninterrupted power supply with an external 4.8 kWh gel battery bank, suitable for mains‑assisted, off‑grid and portable power applications.

• Includes: main UPS unit, 2 x 200 Ah gel deep‑cycle batteries (4.8 kWh total), 1 m tinned copper battery cables, battery linking cable, thermal over‑current circuit breaker, loose ring terminals for crimping, and PC connection cable.
• Power: nominal battery voltage 24 V; continuous output 3,000 W / 3,000 VA; surge power – see user manual.
• AC output: 230 V AC; 50 / 60 Hz selectable; pure sine wave output.
• Solar & charging: solar input power up to 1,200 W; maximum open‑circuit PV voltage 80 V; maximum solar charging current 50 A; maximum mains AC charging current 25 A; maximum combined charging current 70 A.
• Efficiency & cooling: peak efficiency 93%. Ring terminals for crimping. Please note: the inverter uses predictive cooling logic to activate the fans, and is not suitable for continuous fan operation.
• Battery (per battery): 12 V nominal; 200 Ah (10 h rate) / 205 Ah (20 h rate); maximum charging current 40 A; self‑discharge
• Inverter size & weight: 33.4 x 28.5 x 10 cm (13.2 x 11.2 x 3.9 in); weight 6.3 kg (13.9 lb). Supplied with PC connection cable and terminals for mains power connection.
• Operating temperature: -10°C to 50°C (14°F to 122°F). Peak efficiency 93% and suitable for mains, generator-assisted or off‑grid use.

Compatibility & safety: this UPS uses an off‑grid hybrid inverter — do not connect other AC sources or parallel systems without correct isolation and professional installation. Please refer to the Installation tab and supplied user manuals for full wiring, safety and download links.
