Sorry, not the best image, but a shot from Google earth. I circled the 2 panels and North. Problem is that this section of our roof gets the most sun during the day in summer as the rest of the roof is mostly in shade mornings and afternoon. I did want to cut down every tree, but the bigger ones are neighbours trees mornings and afternoon, so that wouldn't happen. We looked at every option, this was the best and most efficient.

Thanks for the help. But should the panel be connected a different way to be more efficient then?

Thanks for this. Yes, panels were all installed to spec by the solar specialists. They also recommended we go with those 2 panels due to the space on the roof. Limited there unfortunately. But I see the battery spec or sticker says it can go down to cut-off at 20V, but how do I know if the inverter is cutting of at 21 or 22V? I have a feeling the inverter is shutting off around 24V. Maybe a safety net or something that the GeeWiz guys reconfigure in the inverter? Can this be checked and changed somehow?

HI everyone. Please bear with me on this, fairly new to the whole solar and backup thing. I have included images of all the inverter specs, the battery specs and also the WatchPower settings for reference. Just after lockdown, we purchased this Mecer 3KVa inverter. It has 200AH of back (So they say...) from the 2 included 24V 100AH Lithium batteries. So due to all the constant outages we have in our area lately, we decided to put up 2 LARGE solar panels. This was done 1st of April this year. The panels we put in are 2 x TigerNeo 72HL4-BDV 585W solar panels on the roof facing east... It was summer! Yes, I know... This is all working perfectly, but now a few little issues I have with this whole setup. Unfortunately, this WatchPower software is all that you can apparently use with this inverter, unless you spend copious amounts on money for that Solar Assistant software. Not happening from my wallet unfortunately... I have this software installed and running on a little Pi that I had spare here with Windows 10 on so I can remote into it and see what's going on. I have just taken a screen shot of it which is below and this winter sun is just not the greatest right now. The settings are the big thing. Are we just extremely limited to what this inverter can do or how can I set it to keep the batteries as close to full as possible, especially in winter? Reason is that 90% of the time when the power cuts, it will be late afternoon or at night and the batteries are just never full and then the system cuts off because of that! It's so annoying and yes, this has been the case for the past 4 outages we had over the past 3 weeks. Then the sun just isn't enough to keep things running the next day and charge the battery... So (sorry for the long story...) my questions... 1) is there anything I maybe need to tweak in the settings there to get better performance from the batteries? 2) How do I know what voltage the inverter cuts off at and what should it be and how do I set it? 3) Any other free alternatives to this WatchPower software? Thanks in advance for the help.🙏
