Hi guys, I have a Victron 48/3000 Easysolar MPPT 150/70 installed with 12 x 300w solar PV panels facing due north at 26degree pitch as an Off-grid unit for a shed a few months ago and the support from supplier non-existent so I've come here to ask for help. I currently have only an inverter fridge and internet & light connected so load is usually sub 100w as shed is still under construction but when complete I had planned to run tools etc and low level domestic usage. At this stage the SOC is consistently declining despite constant warm sunny days and when I plug in a 3600w generator it supplies the load (useful for when I'm using power tools for construction) but does not charge the batteries? In the morning on full sun the colour panel says it's supplying sometimes up to 900w but this always declines despite the batteries lowering their SOC during the day. I may have the wrong expectation but I thought in full sun a system like this should deliver plenty of power? How much power should go into the batteries in full sun? How much power can I expect out of the system in full sun? I was hoping to run all my workshop equipment off it in full sun. I have zero experience in electronics and despite several attempts to contact the supplier I am getting no joy...any advice on perhaps something simple I'm not doing? No instructions were offered on installation and I can't find a user manual online for this system either. I have once in my frustration connected the generator and switched the Inverter to Charge Only and this seemed to kickstart it all back to life but I'm not even sure if I'm supposed to do this? Just a female...so go easy ;)
