Hi all, I have 4 x (Nava Solar TD-LFP-48100RM) Batteries in parallel connected to my 2 x Growatt SPF 5000 ES inverters. The inverters is talking to the main battery and reports that there are 4 batteries connected. My issue is that with each battery having a theoretical capacity of 4.8kw I should have a capacity of about 16kw in battery storage. But it has been running now for two weeks and initially I only had 4kw discharge from the batteries before they where empty and after a week I have about 8Kw discharge. So it seems to me that there is a balancing issue with the batteries. When the inverter reports that the batteries are at 25% all the lights on the NAVA solar batteries reports the same battery level. Does anyone know how to remedy this?

Hi I am building a new steel structure next to my house which will provide shade and will be the home for 16 550W panels. My question is, can I mount the panels straight to the angle iron and lip channels that form the roof of the structure with washers and stainless steel bolts with nuts? Or is there a better way of mounting them without using expensive rails as there will be nothing below the panels only empty space. Unfortunately I can't put the panels on my house roof as it is thatch.
