That great, I have 2x inverters . 3fans per fan.

@PowerUser I used historical data. Measured power output before the fans installed vs power output after the fans. My concern was overheating and deterioration due to high temperatures. this temp reading is before the fans. Max yield from the sun was about 5kW. . inverters After the fans were installed. I am always at 90% efficiency. over 7kW yield. and temperature is within the 45-60deg as per reading taken today.

@madness_za, update on this. I put 6x computer fans to help cool the inverter. The results are amazing. I get 20% more efficiency and the inverter is always within the 45-60Deg range

please share what you have in mind. I am seeing alot of people go that route. I logged a support query with sunsynk and they advised both should be 40-60deg. ill start with PC fans and see how that goes.

I am getting confused regarding what operating temperatures my Inverters should be at. I am running sun5kva hybrid inverter which is documented to operate 40~60 ºC, >45 ºC Derating. this is from the Datasheet. Now when you look at the inverter readings there is two temp readings. DC and AC. which one should be kept at 40-60Deg? I see the AC temp is regulated and inverter internal fans kick in when this goes over 60deg. However the DC temp goes over 75deg. can someone advice which is important and should be within 40-60Deg? attached picture of the temp readings.

If you have a house with a 3phase supply. what is better: 3x single phase inverters? or 1x three phase inverter? What are the pro and cons for each setup? im leaning towards 3x single phase inverters. Only because if one fails I’ll have two phases still working.

Update on this topic. The geyser was replaced. QQ: must a geyser replacement come with a COC?

you're correct, I read and understood it wrong. based on what the others say about. Then for my use case: Ensure that eskom powers the house between 02h00 and 05h00 am. there is now way that this can be achieved on Growat without manually changing the charge priority to SUB. Parameter 50 as now i understand it. will turn of power to anything that is outside of that time set.

Growatt Setting 50 does not work. I have setting 50 on 0103 first two digits: Start hour: 01h00 the last two: End hour 03h59 as soon as i hit enter. lost entire power to the house. Put it back to default 0000. can you share your settings @buyeye?

so im reading the manual. it states the following four 0000. digits for setting 50. AC inverter charge: I have setting 50 on 0103 first two digits: Start hour: 01h00 the last two: End hour 03h59 testing will be if this does not break

im exploring that option thanks. i have not seen anyone use it. testing will be done tomorrow

Wanted: Pylontech 3x UP5000 to buy or option to Trade for Sunsync 5kw Inverters. They must be new. if you're in gauteng - pretoria i can collect them tomorrow

Update on my side: So insurance replaced the Geyser for a like for like. I am exploring parameter 50 on the Growat without them being temperamental. If this work then life is all good. @Sc00bs, unfortunately i dont have any north facing roof area for a geyser. i'll have to manipulate the growat to be functional. If not then i can justify an upgrade to deye and get the time of use settings

Fair enough, I shall do a like for like replacement on the geyser and look at other ways I save the battery utilisation in the morning. i need to investigate a DIY automation on growat to switch from SBU to SUB priority without manually attending to the inverter.
