Indeed, best to have one inverter at a time, otherwise you might trigger inverter envy

The supply dropping is simply clouds going over your panels. By battery disconnecting I assume you mean the State of Charge has little dips? That is most likely not a serious issue. The State of charge is calculated using an algorithm and is an estimate of the charge. As your battery fluctuates between charging and supplying the voltage will change slightly which will influence the State of Charge calculation.

It comes down to software. The Deye has a very configurable daily schedule. As far as I know the Solis is slightly less configurable from what I understand a co-worker told me. He has a Solis S6. Maybe look into that.

The first thing I would check is if the inverter is properly grounded. Once you rule that out, the issue is most likely with the filter on the AC output stage or some sort of missing shielding perhaps? Do you have an oscilloscope handy? Does the AC output look ok?

The inverter AC is definitely worth it. I have three installed at my house and I run all three at the same time on my 5kw Deye inverter off batteries/solar. Check out ACDirect their prices are decent.

Possibly one of two things usually, the gas needs to be topped up or the cap died. A technician will find and fix it fast.

I would keep it simple. I would connect the two geysers up as non critical loads so the inverter will push power to them if there is excess solar and battery. On top of that I would put the geysers on timers so they only charge during daylight hours when you are most likely to feed them with solar directly. I would not make the one geyser feed the other.

Probably not a good idea to alter electricals in a house you do not own. I would revert the changes pronto and pray the landlord does not find out. Good Luck.

Wise words, I used to be a landlord and if I heard the tenants were making changes to the electrical system I would be very upset, not only does it invalidate my insurance, but it is also not their place to make any changes to a house they do not own. What happens if the tenant electrocutes themselves, not a good situation.

Ask the agent for their PPRA registration number and report them: https://theppra.org.za/article/how_to_register_as_an_estate_agent_ Once you get the number, check that they are actually legit as well. If they are not legit you can claim back all the money and fees you paid to them in the past.

Good point and the Normal light has gone off as well. You could possibly try running the battery in percentage(%) mode instead of lithium mode. It is on the battery screen. Another thing you can try is to disconnect the comms cable between the battery and inverter to check if the battery is sending bad info to the inverter. If the battery is ok, the inverter should be able to use the batteries quite easily without the comms cable. Should be a good experiment.

Nothing on the two images has changed, The SOC is still the same.

If you are running a Deye/Sunsynk, Load First would be preferred as it means it will prioritize sending power to your essential loads and only after that is satisfied will extra power be sent to charge the battery.

The SOH is calculated using an algorithm on the BMS. I would reconnect the batteries and ensure both fully charge and possibly go through a discharge and charge cycle and check the SOH again. The algorithm should by then have reset and calculated the SOH correctly.

I just wonder if the isoboard will degrade over time which might cause issues. I don't think those boards are designed to be buried in between fiberglass and soil.

It is no longer fashionable, but large roof overhangs are very good at keeping a house cool. Not only do they keep the sun from shining on your walls and windows, but underneath the overhangs you can put louvres. If there is any breeze, air will get pulled in the one side and sucked out on the other side of your roof. I previously lived in a house that had little triangle louvres at the top of the roof as well as on the overhangs. It worked amazingly well. That house also had ceiling insulation which made a massive difference. On a hot day the ceiling is usually very hot to the touch, but much less so with ceiling insulation. I would recommend you look into "passive house" on google. There are lots of resources available on how to better insulate your house and how to optimize energy efficiency.

I doubt it will make much of a difference. The vast majority of heat loss in a swimming pool is through evaporation at the surface. I good pool blanket that stops evaporation will be your best bet. However I have never tried pool wall insulation, but I have experimented with pool blankets which make a massive difference (5 degrees C hotter or more)

Should be fine, if the battery is the same.

You might also want to check for signs of the cells swelling. What did you configure your max charge rate to be?

This is quite normal. I used to see this with my espresso machine which has a beefy pump for pressuring the water to 15 bar. Things that improved the flickering: - Adding more batteries in parallel. - Going from a 12V to 48V system. - Installing better quality LEDs in the house. - Installing a stronger inverter. I went from a 1000W to 5000W inverter. - Install a pump starter. From my understanding it is basically just a big capacitor over the terminals that can deliver a large current burst when the pump starts.

There are two ways. 1. Disable time of use. Then the inverter will operate as a UPS and only use battery when grid is down. 2. Enable time of use and set minimum battery to 100%.

Those lines are probably for REDZ7 and REDZ8, they will be used in future: Actual power lines: The pink ones are 400kV and the light blue ones are 765kV so there is plenty of infrastructure to get power from the REDZ to where it will be used. Special note for the electricity nerds, the purple lines are DC lines running up to the Cahora Bassa Hydroelectric dam.

There are certain designated areas for renewable energy development zones (REDZ) in South Africa, they build everything there. https://www.csir.co.za/renewable-energy-development-zones
