    Re: Trailboss inverter

    I have a Banggood 750/1500W PSW and the fan comes on at 40W and at over 75W it is full on. On the other hand the Changi/Topshak 1500/3000W the fan only comes on round about 280W. The China specs are...

    I am not sure you will find a 20W with 6hrs run time without a separate solar panel as required.

  5. Re: Portable Solar panels for portable Inverters

    Re: Geyserwise vs Geyserworx

    Yes I fully agree if one can spend the $ on a Sunsynk. Also my top pick. I just think a lot of members use solar for geyser power saving as testing the water using solar. I could be wrong.

    Re: Geyserwise vs Geyserworx

    Great reply and just wonder why we don't see more people going the grid tied route. Even it it means having a 2nd grid tied inverter combined with a back up/true hybrid. They are a no sweat solution.

    Re: 12v or24v power supply for weaco fridge?

    The hot PSU must just be due to the design. A cheap China switched mode power supply should not run hot at 2A full time use for the 5A version.

    It might be a Delco alternator and many other vehicles use them. As said most things inside can be changed. After the regulator it normally is brushes and then bearings around 180th km.

    As the inverter can draw 13A to output to the load circuit I will for sure put it on it's own MCB. Yes you must have a DC fuse or better a DC MCB between the battery and inverter. If the inverter...
