Zendure SolarFlow 4000 Mix AC+ Energy Storage System

Zendure SolarFlow 4000 Mix AC+ – High-Capacity AC Coupled Energy Storage for Balcony Power Systems

The Zendure SolarFlow 4000 Mix AC+ is an AC-coupled energy storage system designed for balcony power plants (Balkonkraftwerke). With 8 kWh of usable capacity and 4 kW of both charge and discharge power, it bridges the gap between solar generation and household consumption.

• 8 kWh usable capacity stores surplus solar energy for use during evening and night hours
• 4 kW max discharge power supports multiple household appliances simultaneously
• 4 kW max charge power enables full replenishment from balcony solar arrays in a single day
• 80 kg compact design fits standard balcony mounting configurations

What sets the SolarFlow 4000 Mix AC+ apart

The AC+ variant integrates directly with the existing AC grid connection of a balcony power plant, eliminating the need for a separate DC coupling inverter. This modular approach allows the battery to be added to an already-installed system without replacing the solar inverter.

Ideal for...

Homeowners with balcony-mounted solar panels who want to increase self-consumption of solar energy and reduce reliance on grid electricity during peak evening hours. Suitable for apartments and homes with limited roof space where a full rooftop battery installation is not feasible.

1. Install the unit on a balcony or near the balcony solar panel array
