The Sungold Power CoreX 5 Elite is a residential energy storage battery designed to hang on a garage or utility-room wall next to your inverter. Each unit stores 5.12kWh at 51.2V (100Ah) in a 1P16S LiFePO4 pack built from EVE Grade A cells - one of the most widely used cell manufacturers in stationary storage - and is rated for 5,000 cycles at 100% depth of discharge while retaining 80% capacity.
A 100A smart BMS with multi-layer protection and cell balancing manages every charge, and the front LCD shows state of charge, voltage and current at a glance. Wi-Fi and Bluetooth connect the battery to the SunGoldPower app for real-time and historical data. CAN, RS485 and RS232 ports provide closed-loop communication with SunGoldPower inverters and most major brands, including Sol-Ark, EG4, Growatt, Deye, Victron, Schneider and MPP Solar.
Start with one battery for essential backup and expand as needs grow: up to 15 CoreX 5 Elite units parallel on one bus for 76.8kWh of storage. It is backed by a 10-year warranty.
