I thought seeing as though one cannot cool down solar panels or cells, one could cool off your geyser mppt and inverter to increase the efficiency of devices. It is sometimes very hot to touch especially the GTI. I have a very warm garage in summer(asbestos roof) so I have attempted to extract hot air with fans and piping(ongoing project). Am I the only person being paranoid about these things (reducing heat sink temperature) in order to gain the maximum power output?

Does the temperature of the 4.6 K GTI look correct? I have a medium sized fan drawing air from the top of it in my garage.I have seen the inverter hit 50 degrees. The manual states Ambient operating temperature range is -25 to 60 degrees.

This is why I installed the PV version to heat water .Too many water heating issues with external thermal heaters especially in summer.

I use the Geyserwise dual mppt with 4 x330watt panels which give me a second geyser/battery store option to be used for other loads of a 24/48v bank.

@DeepBass9 I bought a R200 probe/sensor(variable) normally used for an incubator.That was connected to my irrigation transformer (16v) which fed a solenoid on the valve I used which rerouted my pool water on to my roof on sunny days or when the temperature was warm(adjustable) enough for pool heating.

Hi Chris, Thank you for the advice.I wanted to add an individual voltage display (attached) to each battery as well as the HA02.Would it not be wise to add it then as it is two devices across terminals? Another question is why monitor midpoint and not individual battery voltages or is that an expensive route? If you are monitoring temp, are you using something like this -https://home-assistant.io/docs/installation/raspberry-pi-all-in-one/

Hi New to the forum. I don't know if this topic has been covered. I would like to know what the correct fuse to use for the HA-02.It's a new 12v x 4(180ah) Omnipower bank. Optimizing current 0-10amps and the Quiescent Current 5ma's. Would it be safe to say the draw won't be more than 10amps between batteries as it is new and I will be safe with a 5amp fuse? if the Quiescent Current is 5ma's, can it be even lower(the fuse)? It will be connected to the 4kw Axpert and the load will be lighting for now. Thanks.
