Replacing a converter/charger with an inverter

So is this fuse for the Battery or the inverter/charger? Specifically it would be conceivable to have two one close to the inverter and one that is close to the battery. (Sportsmobile does not install a fuse just for the battery). Since both the battery and the charger are power sources you should have a fuse close to each.

Now moving to attaching the cable for your fuse panel. I would suspect that your wire size has dropped so that too would require a fuse or circuit breaker, again this should be close to where the power source. Looks like you are showing some form of circuit breaker there.

I would also move where you attache the solar controller power through it's own fuse block, a Blue Sea MAXI fuse works good here. This should be close to the controller as it is the power source. Depending on the length of cable between controller and the power connection, you may want to fuse the other end, as it would considered a change of wire size from a power source.

If using a good class T fuse holder like the Blue Sea Models you can safely attach 4 wires to the terminal

This is a quick drawing to give you the basic idea



Hope this helps, feel free to PM if needed.

Hey Greg, thanks for the info.

You answered my question.

The 300a fuse is a terminal blue sea one on the house battery post, from there I have 5’ of 2/0 to the input of the blue sea battery switch, from the output side it goes to the Kisae 2000w inverter Charger dc terminal. The Kisae manual didn’t call for a fuse next to its DC terminal. It only recommended the 300a fuse between its dc terminal and the house battery and it recommended that the fuse be close to the house battery.

From the battery switch output side I did a 6” 8awg jumper cable to a 30a modified reset circuit breaker (mrcb). On the other side of the mrcb is a short 8awg to the blade fuse panel. I have 30a fuse on that panel then about 15-20’ 8awg to the mark 22 solar panel controller that has built in fuse holders and 25amp fuses, one for the solar panel and the other for the house battery.
