Extend existing photovoltaic systems
AC coupled storage system
It is summer, the sun is out and not a cloud in sight. A perfect day for your photovoltaic system, isn't it? It is, in principle. But in most cases your photovoltaic system produces more energy than your household consumes during the day. While you have to feed surpluses into the grid without electricity storage and buy them back at high cost at night, the RCT Power storage system helps you to make better use of the yield of your photovoltaic system. The AC coupled storage system can be easily integrated into your existing photovoltaic system.
AC coupled storage system for your solar power
The feed-in contract for your photovoltaic system is about to expire. Follow-up contracts providing a fair feed-in tariff are increasingly rare. You will receive very little money for the electricity you feed into the grid. There are alternatives, and here you have arrived at the right solution for you. An AC coupled storage system will save you real money. The AC coupled storage system is specifically designed for the scenario when your PV-system requires retrofitting. After the installation, you can store the electricity you generate with your PV-system for later usage. You consume power when you require it. Are you planning to install a new photovoltaic system?

AC-coupled storage system - retrofit power storage
As initially mentioned, an AC coupled storage system is used to retrofit an existing PV-system. The core of the system is a so-called battery inverter that converts the direct current generated by the PV-system into alternating current to be used in the household. The battery inverter simultaneously stores the power gen-erated by the PV-system in the battery storage. You can use your electricity irrespective of whether the sun is shining or not and whenever you want.
AC coupled storage system - build and function
A modern Pv storage system has switching outputs that are easy to program. These switching outputs ensure that any excess electricity from the PV system is not routed to the power grid, but household consumers instead such as heat pumps or electric cars. An AC-coupled storage system has the advantage that it uses high voltages, keeping the charging and discharging currents low. This approach minimises the temperature cycles in the battery and results resulting in a significantly extended battery life.
AC coupled storage system - benefits
There are numerous benefits of retrofitting an existing PV-system with an AC-coupled storage system. The battery storage system will provide you with a new level of autonomy, flexibility and self-sufficiency. The battery inverter will distribute the solar power according to demand. This increases the yield of the PV- system significantly and also helps to preserve the battery.The switching outputs of the system are freely programmable. Heat pumps, electric cars and other domestic electricity consumers are controlled individually and reliably supplied with power. We have also equipped our AC coupled storage system with a very efficient heat sink that provides noiseless and maintenance-free cooling. With our AC coupled storage system, you will optimise the way you use the electricity generated by your PV-system.
AC coupled storage system
- connect it in just a few steps
You can connect the AC coupled storage system without tools via Plug & Play. Use the RCT Power App for commissioning. The AC coupled storage system has a compact and lightweight housing. It is easy to handle, but at the same time, durable and robust. It is connected directly to the existing PV system. The AC coupled battery inverter receives rectified direct current from the PV inverter. It then converts this current into al-ternating current for use in household consumers. The battery inverter can also convert AC power back into DC power. This is a prerequisite for the ability of the system to store the generated solar power in the battery.
