December 20, 20223 yr Author I have installed 2 x ac fans (10cm x 10cm) above my sunsynk inverter. It doesn't go above 60 on hot 2 hours ago, Be4dawn said: Hey guys I noticed now on my app that my inverter Dc Temp is running at around 80 Degrees. Is this normal? inverter was running a big load at the time I checked. AC temp was around 66 Degrees but could not hear any fans running? At What temp wil it be to much for the Inverter? days. I suggest you do the same.
December 20, 20223 yr Ive just put 2 fans at the bottom of the inverter blowing through the fins it helped. Would you say its better to have them on top? Then I assume they have to extract hot air?

Then I assume they have to extract hot air? I'm not sure which is better. I put mine on top extracting because it was easier. Didnt have to try mount the fans at the bottom. Mine just sit directly on top of the heatsink
January 24, 20233 yr Hi Guys, Coming to the party here - I'd like to install some fans on my Sunsynk 5kw inverter and Sunsynk Battery. Thinking of using PC fans fitted with a filter to prevent dust build up. Has anyone done this? Anyone know easiest way to wire the fans?

Thinking of using PC fans fitted with a filter to prevent dust build up. Has anyone done this? Anyone know easiest way to wire the fans? the filter will slow the dust build-up but best to keep spare fans around to replace as they will fail at some point... unless you want to start messing around inside the inverter trying to find 12VDC it's easier to just connect to the fans to a 12VDC power supply. I've just recently setup 2 x 92mm PC fans below the heat sink, using a simple 12VDC PSU but I've got the PSU on a smart switch and using Home Assistant to monitor the inverter's radiator temp and turn the fans on/off as needed... Here's a post that started about the benefits of using fans...
January 24, 20233 yr Thanks man - what is powering your 12VDC power supply? Or did you modify an existing power supply to power the fans?

January 25, 20233 yr Some temps my end - its been VERY hot in Pretoria . I do have a big fan blowing up and a smaller fan at the top pulling hot air
January 27, 20233 yr I see the inverter normal running temperatures are quite high.... Size (W x H x D) - 330 x 310 x 172mm Weight - 11kg Internal Consumption - <1W (Night) Running Temperature - -25°C-65°C Ingress Protection - IP65 Noise Emission - <25dB Cooling Concept - Natural Cooling Max Operating Altitude - 2000m Designed Lifetime - >20 Years Operating Surroundings Humidity - 0-100%

January 27, 20233 yr you can 3d print this fan housing, attach 2x92mm fans with power supply, and mount to the bottom of the inverter...works very well... https://www.thingiverse.com/thing:5224913
January 31, 20233 yr What's the deal with this picture of Sunsynk 5kW that has a fan: Can find it on a few websites. https://www.arsolar.co.za/product/5kw-sunsynk-invertervat-incl/ Edited January 31, 20233 yr by DrLoLCat

Like it has a place for a fan!
June 7, 20242 yr i use a 340mm long cross flow blower at the bottom of mine blowing upwards over the heatsink its on a timer plug its only 35db producing 100cfm
