The deal seems well priced. You battery is 2,56kWh, not 25,6kWh https://nova-craft.co.za/product/felicity-solar-25-6v-2-56kwh-wall-mount-lithium-battery/ You need to check the max power each of your devices use. Let's use some approximate numbers, laptop, typically 50W under full load. lets work on 30W average if in use. 30W X 6 =180Wh (the laptop may well be much higher depending on the CPU in use and also if it has a dedicated GPU. monitors in use probably also 30W if in use. 30W X3 = 90W. 90W X 6Hr = 540Wh Fibre and wifi together probably no more than 10W. 10W X 6Hr = 60Wh Gas Geyser you can ignore. It only uses minimal power on start up. 6 X 10W lights = 60W X 6Hr = 360Wh at a guess thus you would need ~1140Wh This battery has 2560Wh. So you will use approx 50% or less of the capacity based on my thumbsuck best guesstimate

Anyone ever dealt with this company? https://sasolarexperts.co.za/

Anyone on this forum ever purchased anything from PMB Solar? Just trying to establish if they are legit. Seem to be from the website, but with so many dubious websites, just wishing to check if someone in the Pietermaritzburg area has ever dealt with them. https://pmbsolar.co.za/

Open question to those in the industry This accreditation is supposedly issued by the SGCCB. Who is this board and how does one get in touch with them? I see a lot of the solar water heating suppliers/companies pride themselves with this accreditation but a search on the net does not provide a home page for this. Thus if anyone knows of them or has some contact info for them, I would be very thankful

So true, Also running an off grid system. My winter production is always higher than summer. If I were to max out the potential in summer with a constant load, then the summer numbers would be higher too. The week between 15 to 22Jun was particularly low due to the cloud cover mostly, with last Sunday being my lowest ever for one day at just over 4kW from the panels for the whole day. This is what my last 12months looked like. and the sudden drop in production from 15 to 22Jun is clearly visible in the "last 30 days" graph.

"Freedom and Democracy" in all it's glory. As intended. And they stand in queues to vote for more of the same. 🤡

Are you using a standard LAN cable for the comms? You will need to verify the pinouts for both the Inverter and Battery to make up a cable if both are not standard pin outs. You will have to get a similar schematic for battery and Inverter.

Do you have a weblink for that offer?

Was your's installed without a Geyserwise control, as that manages the exact issue that you are now experiencing. It activates the pump conditionally, i.e. you set it to a differential temp trigger. Once that set value is reached, the pump starts until the temps are equal again.

Thank you for the progress reports @Scorp007 Wish you a speedy and permanent recovery from this re-occurring ailment @TaliaB

Trust that will solve the issue. Looking at your log, the big jump was from 51% to 78% in 1 minute. With that size battery that is virtually impossible. I would run that battery down to shut off and then do a full recharge. That should reset the SOC.

My current solar installation had one prime reason only. Independence, i.e. not to have to rely on a government service that may or may not work. Even if the costs of the system and maintenance over a 10 year period happens to end up to cost the same as what I would have paid Eskom, having uninterrupted supply is a blessing. Of course their kWh prices will inflate every year, thus the longer my system is in use, the bigger the saving becomes. The capital outlay is not cheap, but it's a lot cheaper than the new shiny 4 X 4 that is not really needed.

As said, I had two failures in 5 years and the pumps only have a 1 year warranty. All of them had strainers and there was no evidence of dirt. The last pump I now have worked well until the panel became an ornament. This pump actually has a brass housing.

As said, I only stated my experience which was not up to expectations unfortunately. Others may have had different mileage. In hindsight I regret not paying the extra and getting an evacuated tube panel rather than the flat panel. Anyhow @Lucang the unit my friend had installed is this one https://www.pi2r.co.za/product-page/pi2r-micro and https://www.telemetric.co.za/micro.html which is fed in his case by 6 X 250W panels which he actually bought second hand from someone that was upgrading panels. This unit targets 90-200VDC. Thus if you were to get lets say typical 3 X 550W panels that currently go for around R1600, then you are looking at R4800 for the panels, and in series around 150V, right in the ballpark. He also added a timer on his DB to set time windows when he allows the Grid to heat the element. He mostly has the Geyser Grid fed CB switched off and actually switches it on manually on the occasions of low solar input. His installer was a Leon Erlank. If you want you can contact him to see how much info he is prepared to give you for a DIY job. 081 024 1683
