What it is, and what it is for
Growatt APX high-voltage LiFePO4 battery, 5 kWh to 30 kWh
The stackable high-voltage battery for Growatt's MIN XH-US and SPH hybrid inverters. Each APX 5.0P module holds 5 kWh (4.5 kWh usable) of cobalt-free lithium iron phosphate cells; the system is one power module on top, which carries the battery management and the DC-DC stage, with one to six battery modules stacked under it, so a home starts at 5 kWh and grows to 30 kWh by adding modules. Choose the total capacity from the options above; every option includes the power module.
The stack runs at a nominal 385 V (330 to 450 V), which is what lets the MIN XH-US charge and discharge it at full inverter power with small currents and thin cable. It is rated IP66 for outdoor mounting on a wall or the floor, works from -10 °C to 50 °C, cools by convection, and talks to the inverter over CAN. Each module weighs about 50 kg (110 lb) and measures 690 × 185 × 295 mm.
Sizing: 5 kWh carries a fridge, lights, internet and a furnace fan through a night; 10 kWh adds a well pump and some cooking; 20 kWh or more is for a whole-home backup with air conditioning or an EV charger, paired with the 10 kW or 11.4 kW MIN XH-US and the ATS-XH-US transfer switch. The system finder sizes it from your loads. 10-year warranty. Specifications are from Growatt's datasheet and are for reference; the installation must follow the manual, the NEC and local code, be carried out by a licensed electrician, and the interconnection approved by your utility.

Before you order.
If yours isn't here, ask an engineer. It costs nothing and it's the step most people skip.
What if I'm not sure this is the right product?
Ask before you order. Send us what you need to run, or your pool or well figures, and an engineer will confirm the choice — it costs nothing. Or use the finder below, which sizes from what you actually run and shows its reasoning.
