SunGold Power Powerwall X 51.2V 200AH Lithium Battery

The SunGold Power Powerwall X 51.2V 200AH Lithium Battery Stores 10.24kWh in One Wall-Mounted Unit

The SunGold Power Powerwall X 51.2V 200AH Lithium Battery (SG48200T) is SunGold's largest single 48V wall-mounted battery. It stores 10.24kWh of energy using lithium iron phosphate chemistry, enough to carry many households through an evening or a power outage, and SunGold lists UL1973 certification for this model.

SunGold describes the SG48200T as designed for maximum storage, collecting energy from solar during the day and storing it for use at night, during blackouts, or in emergencies. It pairs with SunGold's 48V all-in-one and split phase solar inverters, and SunGold includes it in several of its off-grid solar kits.

SunGold Power Powerwall X 51.2V 200AH Lithium Battery Features

10.24kWh of Storage in One Battery

At 51.2V and 200Ah, one SG48200T stores the same energy as two 5.12kWh batteries. That means fewer units to mount, wire, and manage.

LiFePO4 Chemistry

Lithium iron phosphate cells offer a stable, long-lasting chemistry well suited to daily solar cycling and backup power.

Built for 48V Solar Systems

The 51.2V nominal voltage matches 48V inverters. SunGold uses the SG48200T in its 8kW and 10kW off-grid kit options, paired with its split phase solar inverters.

Optional Wall Mount Kit

SunGold sells a dedicated wall mount kit (SG48200T-WMKIT) designed for this battery, so it can be mounted securely on a wall.

Optional Wi-Fi Monitoring

The SG48200T Wi-Fi module, sold separately, provides real-time monitoring of state of charge, voltage, temperature, and cycle count. One module covers a whole system of multiple batteries.

UL1973 Certification

SunGold lists UL1973 certification for the SG48200T, a standard for stationary energy storage batteries.

Real-World Applications

Home solar storage. Store daytime solar for evening and overnight use.

Backup power. Keep refrigeration, lighting, and essentials running during outages.

Off-grid homes and cabins. Build a large 48V bank with fewer units.

Emergency preparedness. Keep stored energy ready for storms and grid failures.

How It Compares to Common Alternatives

Versus two 5.12kWh batteries. One 10.24kWh battery reduces mounting points, cables, and connections.

Versus the SG48100M. The SG48100M stores 5.12kWh. The SG48200T doubles that in one unit.

Versus the PowerMax 314 Outdoor. The PowerMax stores about 16kWh in an outdoor-rated cabinet. The SG48200T is a smaller wall-mounted option.

Is This Battery the Right Fit

• System voltage. 48V systems (51.2V nominal).
• Capacity. 10.24kWh per battery.
• Mounting. The wall mount kit is sold separately.
• Monitoring. The Wi-Fi module is sold separately.

This may be a good fit if

• You want 10kWh of storage in a single battery
• You run a 48V solar inverter
• You want a UL1973-listed battery
• You prefer fewer, larger batteries

Common Questions
