8 x 390W Canadian Solar panels Goodwe ES 4.6kW inverter 9.4kWh Pylontech batteries (2 x 3.5kwh + 1x 2.4kwh) Plus all cables, racks, mounts, etc Everything was installed in October 2019 except one of 3.5kwh batteries which was done in September 2020. The SoH is currently 100% It's all currently installed in my apartment but will arrange for it to be professionally taken down so that the sundries are reusable. Looking for 100k or make me a reasonable offer.

Had the same issue. Goodwe advised to hard reset the system as follows and it started working: hard reboot the device, AC power off, PV off and then batteries off. wait 5 min and then start it back up in reverse. you may need to restart your batteries after this as well

So I have 2 issues and I'm hoping someone here knows how to solve this or perhaps what could be causing the issues. 1) My geyser burst. Insurance replaced it but the people they sent obviously have no idea how to work with solar geysers. For some reason, my geyserwise says the temperature is above 65 but when I shower I get about 20 seconds of hot water and then cold water the rest of the time. Weirdly, the other taps in the house can give very hot water. The temperature on the geyserwise doesn't drop during showers like it used to before the geyser burst. These guys have no idea what to do so have completely disabled the solar and now my geyser is running off the element only. 2) My geyserwise control box keeps blowing up. I've had to replace it 3 times now. It's always during some weird situation as well. The last time it blew, the element was on and pulling 3kw. All of a sudden it demanded 6kw and then died. Any suggestions would be greatly appreciated

My solar system is pretty decent and able to run my whole house off the grid as I long as I dont use more than 2 big appliances. I generally have my Eskom switched off completely and run off the sun and batteries. My flat runs like this 95% of the time. About a year ago, there was a period of around 10 days in jhb where there was no sun. I was concerned that my batteries wouldnt charge so I switched Eskom on to supplement my power. During this time there was also stage 4 loadshedding. One particular day, load shedding hit at the exact moment my fridge compressor started up and it blew up. The house stank to hell of burnt metal for about a week Insurance replaced the compressor on the fridge luckily. Fast forward to yesterday and, after Eloise covered jhb in clouds for like 3 weeks, I switched on Eskom again. No load shedding this time but the Eskom power cut at the exact moment the fridge started up and now 3 components in the fridge have blown. It is now beyond repair and needs to be replaced I'm not exactly sure what is going on here but maybe someone can shed some light on it. When Eskom is switched off, I have no appliance issues. I even use my microwave and kettle at the same time! However when I switch Eskom on and there's loadshedding or similar it seems like I am highly likely to get a blown fridge. Is it because the inverter can't switch between grid and battery/sun fast enough? It was a Bosch A+++ fridge and it is now being replaced with a Bosch A++ fridge and running on a Goodwe with Pylontechs. I find it weird that the fridge can burn components so easily when there's a potential shortage of power. Any advice on how to prevent this would be greatly appreciated. I'm tempted to just switch Eskom off permanently and push my batteries down to 20% if needed.

Can this timer be used to control the solar 12v pump?

Thanks @Vassen! You've got this spot on! I have tubes on my roof and when the water gets very hot (over 75), I get lots of water leaking down my roof! I also have a 12v pump so switching off the electricity supply does nothing. I was actually afraid of the cover up suggestion as there is no way for me to access my roof without getting contractors in. Guess I'll just have to take a chance that the valve is working

Interesting! On "Holiday Mode" mine just seemed to carry on working as normal hence the 91 degree temp in winter!

Even if switched off at the mains the solar pump still runs when the sun is out. One day I had no water and I tried switching the mains off but the pump was just making a huge noise trying the pump nothing. All it says on it is GeyserWise Max

I have a solar geyser with a Geyserwise meter attached to it. . During a normal jhb summer's day, the water quite easily goes from about 30 in the morning to 55-60 by the evening. In winter, it goes from about 20 in the morning to 45 in the evening so I had the element on for about an hour to take it to 65. During winter, I wasn't home for a week and I 'switched the geyser off' using the function on the Geyserwise monitor. However, when I returned home the water temperature was 91! I think the pump still ran when the sun was out even though the monitor said "off". I'm going on holiday for a month soon and I'm really worried that the geyser will explode or something as I don't know how to stop it from generating heat when the sun is out. Does anyone know how to switch it off?

haha. I'm gonna go with UFO! I need more alien tech

What happened at 02:15 this morning? Have my solar panels evolved? 🤨

I just did this on my system. My element is 3.5kW which isnt great but the it's timed to run only when I'm sleeping. I would definitely recommend it to anyone thinking about it as now I don't need to keep resetting my GeyserWise settings every time there's load shedding.

@Bobster, is the 20A limit purely battery or in total (battery + panels)? If you're able to get 20A from the battery plus say 10A from your panels with good light are you not safe in 99% of situations?

Mine does a similar thing when I switch my geyser element on. Even though the geyser is not connected to the system, the inverter will use battery+solar+eskom for it. The only way I've been able to go completely off grid is to switch my eskom mains off. However, the geyser element cannot be switched on unless I put the eskom mains back on. I think that the inverter is clever enough to realise it can "assist" non-backed-up items but unless those things have eskom to start up it cant do anything. Sorry I know this isn't the most helpful but perhaps an extra data point can assist you.

Do you know what the delivery times are? I need to get a 3.5kw asap
