Retrofit AC Coupled battery system to achieve solar self-consumption
A Quick and Easy Way to Achieve Solar Self-consumption by PowerGo
Retrofit AC Coupled Battery ESS
As the EEG law gradually expires and solar power systems become more common, negative electricity prices at midday are happening more often. This means households with rooftop solar are earning less from feeding power into the grid. To save on electricity bills and become more self-sufficient, people really need a retrofit AC coupled battery storage systems. But the high cost of these systems—both the equipment and installation—makes it hard for many to take the leap.
Traditional AC-coupled retrofit battery storage is a hassle
• You’ve got to deal with grid permission paperwork– extra red tape just to get started.
• Your home’s power panel needs modifications– more time and money
• The AC-coupled inverter has to be compatible with lithium batteries by protocol– not all systems work together.
• There’s a mess of cables—power lines, BMS wires, all tangled up.
• Separate cloud apps for inverters & batteries– no unified monitoring.
AC Plug-in Battery ESS
• Just a quick schuko plug in and APP settings, done
Retrofit Photovoltaic AC Storage for Your Balcony Power System
That’s exactly why we developed the PowerGo AC Plug-in Battery – an innovative AC-coupled system for easy AC power storage retrofitting, which can be installed in no time!
Just plug in and you’re done: All you need is a standard Schuko socket or power strip. This is how AC storage retrofitting works plug-and-play without technical hassle – thanks to the integrated inverter and BMS, there are no compatibility issues between the battery and solar system.
Important: The PowerGo AC Storage for balcony power retrofitting operates on single-phase alternating current. Make sure the socket is on the same phase as your PV system!
PowerGo Supports Two Modes for Self-consumption
PowerGo supports two smart operating modes for increased solar self-consumption:
Schedule Mode
Manually set charging/discharging times and power levels. You can set two separate time slots for each. While this doesn’t match real-time load changes, it works well for basic or scheduled loads—no need to touch the electrical panel.
Smart Meter Mode
Requires a wired CT clamp or wireless meter (like Shelly EM) in your electrical panel. With this, PowerGo adjusts charging/discharging automatically based on real-time grid power, maximizing self-consumption.
Control via App
All settings are managed through the PowerGo app—whether for green energy or dynamic electricity pricing. This way, you maintain full control over your solar energy.
