I have 2 power wall units from Tesla on order, but it is backorder indefinitely. I’m curious if it would be possible to connect more than 2 EP500 units, say 6 of them, to have a total capacity of 30.6 KWh, which would be more than the 2 power walls I have on order (13.5 KWh each, 27 KWh total). Is this possible? The website seems to indicate only a max of 2 combined
You can only put two in parallel in a split phase mode for 240 VAC. You must NEVER put two or more in a direct parallel mode as with DC sources, because the AC power will not be in phase as how the power utilities put their generators in phase. I don’t know if the EP500 will allow that.
The only alternative I can see for now is splitting the total load into separate circuits that each EP500 can handle by itself. Maybe in the future some Bluetti/Maxoak engineer can forsee the future of home power and design phase synchronization into every new product for true parallel applications.
Welcome to our community.
It is not allowed to connect more than 2 EP500 at present. It needs our tech workers to explore and will be available in the future.
