September 16, 20214 yr Hi All, What's your ac temps like on your inverter, I have the 5kw with no external fans (Latest model) The heatsink gets quit hot to where its still touchable but almost at a burring stage. Max temp for the day 53.6 Is this a problem or normal? Inverter is in the garage with temps of 24 and a small breez. Will the inverter protect itself when overheating?
September 16, 20214 yr As far as I am aware all Sunsynk inverters have a fan. My 5kW Sunsynk fan comes on at 65 deg C and switches off below 60 deg, with this high temp only when the batteries are taking pretty high amperage charge.
September 16, 20214 yr Strange, what you have in your pic at the bottom of your inverter I have on the top of mine, and when looking from underneath I can see the fan. Temps I gave you are for the DC inductor, and looking at my device graphs the max AC temp is about 45 to 48 deg when running at 2000 to 3000 watts from solar and the fan does not come on. And yes the inverter will trip if it over heats.
September 16, 20214 yr From what I have heard, the newer ones don’t have fans, I originally had a 3.6 kW Sunsynk which did not have a fan
September 16, 20214 yr My 5kw sunsynk went up to 55 degrees today while doing 5kw load for 1 hour, so yea its pretty normal.

At the bottom something looks like a fan but their are no visible moving parts. But one thing to keep in mind these units are IP 65 rated. Designed to work on ship decks and take a water spray without a problem. So if it sits on a garage wall under a roof it might look a bit strange.
September 18, 20214 yr The fan for the sunsynk is inside the inverter box, you can hear it when you open the connection panel and the inverter is a bit hot, I've seen my inverter go up to 65 degrees so i placed two pc fans on the heat sinks extracting air now, so they stay under 50 degrees
October 17, 20214 yr Does anyone know where i can check the temp on a new 5kw unit as mine is also hot as hell and fan continuously running
November 12, 20214 yr In The app it says under temps Battery temp 23c And inductor temp2 -109.99c so somethings not right
November 12, 20214 yr @Convict if you go under device - inverter and scroll down the page, you can see the inverter temperature. I have seen mine going over 56 deg while charging the battery but that shouldn’t be a problem. Edited November 12, 20214 yr by PowerUser
November 16, 20214 yr Seems mine doesn't display Temps. Not sure if it's a fault or just how the new 5kva units are .

The screen you are showing here is from SolarmanPro App. You need to link it to SolarmanSMART App. That one will show you temp as described on the screen above. You can link the same inverter to both Apps.

October 12, 20223 yr So my sunsynk 5kw inverter is getting up to 75 deg, can't hear any fan coming on.... Any suggestions?

Bought this one from Makro https://www.makro.co.za/appliances/fans-heaters-air-coolers/fans/floor-fans/elektra-23-cm-floor-fan-/p/000000000000383947_EA Plugged the UsB fan into the Pi i have by the inverter and that runs 24/7. If it gets hotter I'll use the larger fan also
