This all in one solution with integrated solar, inverter and battery systems is easy to install in any of these 3 configurations:

DC/Solar Coupled: The system is connected directly to a solar system. Ideal for first-time renewable energy installations, reducing cost by removing the need for additional components. Everything you need is inside the OFFGEN.

AC Coupled: The system is connected via existing AC circuitry. This is perfect for adding battery storage to existing solar installations and is as hassle-free to integrate as a home appliance.*

UPS Mode: The system works without solar to protect against power outages or provide smooth power for sensitive equipment. It is an excellent alternative to noisy home generators, which require frequent servicing and incur high fuel costs.

*This refers to hardwired appliances, which require a trained professional.

“Aceleron designed a battery system for us which has enabled us to reach a market dominant position within Barbados and the Caribbean. Thanks Aceleron!”
