Where to buy a reliable and high-performance AC coupling kit?
The AC coupling is an ideal solution to add storage to an existing photovoltaic installation without modifying its original structure. It allows connecting lithium batteries and a coupling inverter directly to the alternating current (AC) part of the circuit, offering great installation flexibility.
At Allo Solar, we offer a carefully selected range of AC coupling kits composed of hybrid chargers, Victron or Sofar inverters, Sofar or Pylontech lithium batteries, and all necessary accessories for a secure integration. These kits are designed for residential installations seeking to optimize self-consumption or to have a reliable backup power supply.
Is it profitable to install an AC coupling kit?
Yes, adding an AC coupling storage system is a cost-effective investment, especially in the context of an existing installation. It allows:
- Immediate reduction of grid consumption
- Maximum use of self-produced solar energy
- Continuity of service in case of power outage
- Gradual upgrade of the installation (possibility to add batteries or increase power later)
The investment is particularly attractive when electricity prices are rising or as part of a smart sizing of self-consumption.
How to choose your AC coupling kit wisely?
AC coupling or DC coupling
This DC coupling often requires replacing the existing PV inverter, whereas the AC coupling kit can be added independently. It is a flexible, scalable, less invasive solution, ideal for installations already in operation.
Choice criteria:
- Power of the coupling inverter: suited to your charging/discharging needs and your installed capacity
- Lithium battery capacity: expressed in kWh, it determines your energy autonomy
- System compatibility: with your existing PV installation (inverter, micro-inverters, grid type…)
- Scalability: possibility to add batteries or connect multiple inverters
Questions you ask us about AC coupling
What is AC coupling storage?
AC coupling storage involves connecting a battery system on the alternating current (AC) side of the solar installation via a coupling inverter. This allows keeping the existing PV inverter and adding storage without modifying production.
What is AC coupling in a solar installation?
It is a method where energy flows circulate in the AC part of the network, unlike DC coupling which occurs upstream of the PV inverter. AC coupling is flexible and compatible with already operational installations.
How does an AC coupling inverter work?
An AC coupling inverter, such as Victron MultiPlus or Sofar, manages the charging and discharging of batteries via alternating current. It can also supply the home grid in case of a power outage.
What are the advantages of an AC-coupled storage inverter?
- Compatibility with an existing solar installation
- Flexibility and scalability
- Safety and continuity of service
- Possibility of configuration in off-grid or self-consumption mode
