The SunGold Power CoreX 5 Pro Server Rack 48V 100AH Residential Energy Storage Battery Pack is a 51.2V, 100Ah LiFePO4 battery that stores 5.12kWh. It is built with Tier-1 EVE Energy cells, a color LCD screen and built-in Wi-Fi and Bluetooth, so you can check the battery on the front panel or from your phone.
It is designed for homes. Use it as emergency backup where the grid is unreliable, pair it with solar to use more of your own power, or shift usage away from high-rate hours. Up to 15 packs can run in parallel as your system grows.
The 16 cells in series are EVE Energy LiFePO4 cells. SunGold rates the pack to keep 80% of its capacity after 5000 cycles at 100% depth of discharge, and backs it with a 10-year warranty.
The app connects locally over Bluetooth with no account needed, or remotely over Wi-Fi from anywhere. It shows voltage, current, temperature, status, SOC and SOH, and it can install firmware updates over the air.
The display shows state of charge, voltage, current, capacity and any alarms. When packs run in parallel, the master unit shows the average SOC, average voltage and total current for the whole bank.
The BMS monitors cell voltage, current and temperature, balances the cells, and protects against over-voltage, under-voltage, over-current, short circuits, and high or low temperature. A 20A charging current limit is on by default and steps in when charge current reaches 90A.
Connect up to 15 packs in parallel. For systems up to 100A, use the included parallel cables. Above 100A, SunGold calls for a busbar connection.
The power cables use color-coded quick-connect plugs that insert into matching sockets, which helps prevent reversed connections. The front panel also has a breaker, a power button and a reset button.
Emergency home backup. Keep household circuits powered when the grid is unstable, using a compatible 48V inverter.
Solar self-consumption. Store solar power during the day and use it at night instead of buying grid power.
Peak shaving. In areas with large peak and off-peak price gaps, charge during low-rate hours and discharge during high-rate hours.
Growing rack systems. Start with one pack and add more on a rack as your needs change.
Versus a wall-mounted battery. A rack battery stacks with others in a rack or sits on the floor, so several packs share one footprint. A wall-mounted battery needs wall space for each unit.
Versus a battery without app monitoring. With Wi-Fi and Bluetooth built in, you can check charge level, alarms and cell data from your phone, at home or away.
Versus a lead-acid battery bank. This pack adds a BMS, inverter communication and remote monitoring, and SunGold rates it for 5000 cycles at 100% depth of discharge.
This may be a good fit if
No. They work one at a time. After you bind the pack to Wi-Fi, you need to unbind it before switching back to Bluetooth.
The pack has both RS485 and CAN ports for the inverter. Use either one, and check that the pin definitions match your inverter.
With the current limit on, the pack drops charging to 20A when charge current reaches 90A. With the limit off, charge over-current protection trips at 96A.
No. Packs can be used alone or in parallel, up to 15, but not in series.
The SunGold Power CoreX 5 Pro Server Rack 48V 100AH Residential Energy Storage Battery Pack gives a 48V home system 5.12kWh of EVE-cell storage with Wi-Fi and Bluetooth monitoring and room for 15 packs.
