Description

Growatt APX 20.0P 20kWh High-Voltage Solar Battery Storage is a modular battery storage system for anyone who wants to make the most of their solar power and increase their independence from the grid. With 20 kWh of energy capacity and a depth of discharge of 100%, the stored solar energy is fully available to you.

Your Benefits at a Glance

High storage capacity: 20 kWh of usable energy reliably powers your household through evening and nighttime hours.
Full utilization: Thanks to 100% depth of discharge, no stored energy goes unused.
Modular design: The storage system can be flexibly expanded with additional battery modules, adapting to your growing needs.
Safe LFP technology: Cobalt-free lithium iron phosphate cells ensure a long service life and a 10-year manufacturer warranty.

The System in Detail

The Battery Modules

The heart of this Growatt battery storage system consists of four APX 5.0P-B1 battery modules, each with 5 kWh of rated energy. They are based on cobalt-free lithium iron phosphate (LFP) technology, known for high safety and a long cycle life. Each module operates at a rated voltage of 385 V with module-based energy optimization, allowing modules with different states of charge (SOC) and states of health (SOH) to be combined within a single system – ideal for future expansion.

The Battery Management System & Mounting Bracket

The Growatt APX 98034-P2 high-voltage battery management system, together with the APX battery mounting bracket, handles the central control and mechanical housing of the storage system. It ensures reliable interaction between the individual battery modules and enables the stackable, modular design of the photovoltaic battery storage system. This allows the Growatt APX 20.0P to integrate seamlessly into your existing solar system and noticeably increase your self-consumption.
