All-in-One Energy Storage System - 6500W Inverter with 5120Wh 48V Battery

Everything a small off-grid or backup system needs, already wired together in one floor-standing cabinet: a 6500W pure sine inverter, dual MPPT solar charge controllers good for 8000W of array, and a 5120Wh 51.2V lithium battery. Instead of sizing an inverter, a controller, a battery, a BMS and the cabling between them, you bolt this down and connect three things - PV, grid or generator, and your load panel.

Why this system

• 6500W continuous pure sine output at 120 VAC, with up to 93% DC to AC conversion efficiency.
• Two independent MPPT trackers accept up to 8000W of PV at 90 to 230 VDC operating range, 250 VDC maximum open circuit. String design still matters; check your array's cold-weather Voc against that 250V ceiling.
• 5120Wh of LiFePO4 storage at 51.2V nominal, 100Ah, with an integrated BMS and breaker. Continuous discharge is 120A with a 192A one-minute peak.
• Combined AC and solar charging up to 120A, and you can set the charge current yourself rather than accepting a fixed rate.
• Supply priority is programmable between PV, battery and grid, so you decide whether the system is a self-consumption setup, a backup box, or something in between.
• Battery-independent design means the inverter will run from PV and grid even with the battery isolated for service.
• Monitoring over USB, RS232, SNMP, Modbus, GPRS and Wi-Fi, with Android and iOS apps for status and control.
• Battery capacity is expandable, so a system that starts at 5.1 kWh does not have to stay there.

Installation

• The complete system stands 49.2 in tall in a 26 x 19.7 in footprint and weighs 287 lb assembled. Plan the delivery and the floor it sits on accordingly.
• Ships by freight. A liftgate and a helper are not optional at this weight.
• Works with utility power or a generator on the AC input, accepting 80 to 140 VAC.
• AC input current is up to 60A, so the feeding circuit and any transfer arrangement must be sized and permitted for it.
• This is a 120V single-phase unit. It will not by itself serve a 240V split-phase panel.
• Have a licensed electrician handle the AC tie-in and grounding.

Compliance

• Certified to UL 1741 and CSA C22.2 No. 107.1-16 for the power conversion side.
• Battery compliance covers IEC 62619 and UN 38.3 for transport.
• Electromagnetic compatibility per EN 61000-6-1, EN 61000-6-3 and FCC Part 15B, plus UKCA marking.
