A 5.12kWh wall-mounted 48V-class module, matched to Deye's low-voltage hybrid inverters.
The battery to pair with a low-voltage Deye hybrid, mounted on a wall rather than taking floor space in a villa store. 5.12kWh at 51.2V nominal, which is the 48V class, with cobalt-free LiFePO4 cells rated by Deye at 6,000-plus cycles at high depth of discharge. Voltage class is the check to run before ordering. Deye builds both low-voltage and high-voltage hybrid inverters, and this module belongs with the low-voltage ones. It will not pair with the high-voltage SUN-30K-SG01HP3 in this catalogue, and confirming the inverter's battery architecture is the step that prevents an expensive return. Once matched, the BMS pairs natively with Deye hybrids, so commissioning is a menu selection rather than a protocol investigation. Wall mounting is a genuine practical advantage in a Dubai villa, where the plant space is often a narrow store, a garage wall or a service corridor and floor area is contested. Floor and rack mounting are also supported per the sibling SE-G5.3 arrangement. Cobalt-free chemistry is the other note worth having: it removes the least ethical and least thermally stable part of older lithium formulations, which is the right direction for a battery living in a hot country.

Match the voltage class before anything else. Deye produces hybrids in both low-voltage and high-voltage architectures, and this module is the low-voltage partner. Pairing it with the high-voltage SUN-30K-SG01HP3 is not possible, and that mismatch is the commonest error we see in a first Deye specification. On a matched low-voltage Deye inverter it commissions quickly and reports through the same platform. Wall mounting earns its place in Dubai villas, where the battery usually ends up in a garage, a store or a service corridor with more wall than floor available, and getting the pack off the ground also keeps it clear of water on a floor. Position it in the coolest ventilated spot you have. LiFePO4 handles heat better than older chemistries, which is exactly why we use it here, but cycle ratings assume sensible temperatures rather than a sealed cupboard in August. No UAE distributor publishes an AED price for this model, so it is quote-only through Nastech and the wider Deye channel. A battery on a backup or off-grid system involves no DEWA process.
