Hello, I am a solar newbie and I recently bought a EB150 for a small cabin along with 2*200w solar panels. However, when I put them in series (or individually as well), the EB150 stays at 0 watt of input. It very briefly goes up, to about 20w for 1 second and then goes back to 0, no charging. It is quite frustrating. Any idea what’s happening? I tried to reset the unit, doesn’t work. Bellow are the details of the panels if it is useful.
Thank you for your help!
