My house consumes well above average. 15,000kWh per year, so 40kWh per day average. I'm still adjusting between self-use and priority export, but on priority export, my battery level has been below 20% before 11pm on a couple of occasions due to dull days. That's fine for now, but during the shorter days of the Autumn and Winter, I would be pulling from the grid before 6pm. My Energia rate is the 2am-6am, so I would need to avoid running out of battery and it helps to supplement with solar for now. When I have 2 batteries and when I can draw more than 5kW, I don't think I will have self-use. I plan to add to my 5.2kWp setup (currently 8 south and 4 north panels), probably doubling it to assist during the short days. This will be done within the next 12 months, probably in 2, or 3 batches. I have space to add 4 more panels to my North facing roof, plugging into an existing string. Then I have space for 4-6 panels on a flat extension facing South and room for 4 panels on my shed which inclines at about a 5 degree angle North, but is essentially flat. I could be cheeky and put 2 more panels on the back of the shed and they would face South, mounted vertically. Lots of potential, but requires another inverter, or micro inverters for the full project.

I have yet to add a second battery to my system. I will be doing this next month. Logic would tell me that the second battery would be set up just like the first battery in the BMS Studio, with the exception that the DIP switch setting would be different than the first battery. The total capacity should update on the inverter. In the event I find this to be inaccurate, I will update here. For now, this is what I have. Assuming you are adding batteries in parallel: On page 26 of the manual for the SEPLOS Vertical 280Ah Battery Pack, the DIP settings for a single battery will be all OFF. When adding a second battery, you need to set the first battery DIP to pin 5 ON. On the second battery, you need to set pin 1 ON. If adding a third battery, the setting for banks 1,2 and 3 are Pin 6 ON, Pin 1 On and Pin 2 ON with respect to each battery in that order. When adding a 4th battery bank, the DIP settings become slightly more complex. Up to 16 battery packs can be connected in parallel according to the manual. Please refer to the user manual for clarification, as the settings are only accurate at the time of this post and may also be misinterpreted.

Small discrepancies seem to be commonplace between the inverter display and the APP. This is not just a Solis issue from what I have read. Like any electromechanical device, there will be a tolerance and this seems to be +/- 300W from my observations without detailed understanding or investigation. I hope that helps.

@@GaryMeatsLife the problem is that I haven't seen it 0 on the device even in peak sunlight hours. The device shows 2 to 3 amps. Could you please also mention what should be the CT direction and ratio and what is the criteria for setting this value?

@@wassaufkhalid8593I’ll pretext this by saying I’m a mechanical engineer and not an electrical engineer, so my understanding on this is limited and is gleaned from reading up on specialist contributions on online fora. The device will use a few amps and this may not be recorded in the APP output. Unless it is causing you to import/export unnecessarily, I would personally not worry about it. The inverter CT should point from the CU to the grid. I can’t advise on ratios. These settings are typically default values on the inverter and may only change when another relevant value is changed. The video is only intended for basic setup guidance. There are other channels which would cover settings on a deeper level. The solar DIY forum is also a great resource to troubleshoot. I’ve used it with good success.
