Good morning, I'm asking for support for an installation problem I encountered over the weekend.
My system currently consists of a multi plus II GX 5000, an Mppt 450/200. Unfortunately, the batteries have yet to arrive, and in any case I wanted to use the power produced by the photovoltaic to support the house. Alternatively when there was no sun, use energy from the electricity grid. However, the multiplus doesn't allow me to do this as it gives me an error:
Low battery alarm
My question is whether I'm configuring the multiplus wrong or whether it actually can't do what I'm asking it to do?
Thank you
