what size fuse should be installed? And location, before controler or after?

We recommend using a 45-50 A fuse with this particular kit since the charge controller is rated at 40 A. This size fuse will ensure fuses won't be blowing all the time if your system is approaching the fuse current quite often and it will also protect the charge controller by keeping it from operating out of the 40 A range by too much. Typically our customers do not use fuses because it is quite rare that the current ratings will be exceeded. However if you do wish to use them, the most important location is going to be between the charge controller and the battery. If over current does occur it will most likely never be on the solar panel side. For maximum protection you can place one on both sides of the controller.

Hi, There is no need for an extra relay in the fuse box, and there is no need for any modifications as well. But we still recommend professional installations only. Thank you

I would always use a fuse in case the diode should fail in the panel or failure of your battery charging circuit/batteries. I've melted plenty of wires to know the value of a fuse. I also need to practice more of what i preach :)

I have 5 of these and did not install a fuse. I have discovered that for practicle installs >10 feet of wire, you need 6ga or double 10ga to reduce voltage loss. This is VERY important if setting up an MPPT system. Its still important for PWM. You can never have wires that are too thick.

probably the fuser, we have used both original and rebuilt fusers with good and bad results. If its not critical, start with a cheaper rebuilt fuser. it should be under 150 USD

I made my own. The controller has terminal strip screws for all the inputs and outputs. I have the controller within 5 feet of the battery. Use at least 12 gauge wire for each, the positive and the negative. Larger gauge would be better. I crimped on connectors to fit on the controller screws and my battery has screwed studs that I also crimped connectors on to fit.

If all accessories are run through this panel the one additional fuse is at the battery. This fuse should be large enough to handle the load of all accessories on at the same time.

There needs to be an in line 20 amp fuse between the battery and the controller. I put mine near the battery.

Should work fine. Like anything else, might want to put a fuse in line though.

I would suggest a 4 guage wiring kit with a 80 amp fuse or higher. I use 4 guage without any heat issues.

I used a ANL 30 amp Fuse along with the Scosche EWFH single ANL fuse holder. Both bought from AMAZON. And play it safe buy two fuses, one for back up.

I didn't install any additional fuses. I'm guessing the ground wire is there to protect the battery connection. It was easy for me to do it, so I did.

Always better to play it safe. Run two seperate legs, you dont want to have all lights out because of a blown fuse. A little more hassal ,but worth it. I know this from expirience.

i put a 150 fuse out side the unt and am very glad that oi did. I short circuted when installing.to ground and only had to replace the fuse

You want to first consult your owners manual for the 1500 wt inverter to see what size and type of fuse they recommend. I have a Zantrex 2000 wt and also another at 1000wt and Mine recommended the ANL Fuse. I have two different size fuses installed in this holder and I have heavy cable connected between the fuse holder and the inverter. Again I would recommend what the inverter manual suggests. The cable you can find here on Amazon. Sorry I am not more help.

Replace that stock fuse with a 15amp fuse. It will be the same size. Hopefully this will fix the problem, assuming you have an Alpine deck, which should also have a 15amp fuse on the back of it.

If 15 amps are needed, then a 25 amp fuse should be used. You want about 20% headroom over the maximum current draw. If the holder has a 30 amp fuse you can just remove it and install the correct size for your application. Do not use a 30 amp fuse for a 15 amp draw, as it could potentially cause an over current condition destroying whatever it is your trying to protect with the fuse.
