Growatt APX 5.0P-B1 High Voltage Solar Battery 5 kWh LiFePO4

Growatt APX 5.0P-B1 – High Voltage Solar Storage for Maximum Self-Consumption Optimisation

The Growatt APX 5.0P-B1 is a modular high-voltage battery storage system based on durable LiFePO4 technology. With a usable capacity of 5 kWh, it is ideal for storing excess solar energy and increasing self-consumption in households.

• LiFePO4 technology: higher safety, longer lifespan and more environmentally friendly than conventional lithium-ion batteries
• Usable capacity of 5 kWh: covers typical evening and night consumption of a single-family home
• High discharge power of up to 15 kW enables simultaneous operation of several large consumers
• Compatible with most Growatt inverters: seamless integration into existing solar systems.

What sets the Growatt APX 5.0P-B1 apart

The storage unit impresses with its modular design: up to three APX modules can be combined to expand capacity to up to 15 kWh. The high-voltage architecture (approx. 360–480 V) ensures higher efficiency in energy transfer compared to low-voltage systems. Additionally, the APX 5.0P-B1 is equipped with active cooling that maintains stable operating temperatures even under high loads.

Ideal for...

This solar storage unit is aimed at homeowners with an existing or planned photovoltaic system who want to maximise self-consumption and become more independent from the grid. For commercial businesses with high daytime electricity consumption, it is also an efficient solution for smoothing load peaks.

How to use the Growatt APX 5.0P-B1

Installation should be carried out by a certified electrician. The storage unit is connected directly to the compatible Growatt inverter and configured via the Growatt monitoring platform. After commissioning, the system operates fully automatically: excess solar energy charges the storage unit, and when needed, the stored energy is fed into the home grid. The state of charge and power can be monitored at any time via the Growatt app.
