Wouldnt you want the spd wired in the pv side of the breaker? The reason i ask is because it seems like the breaker would trip in the case of surge and excess power wouldnt be able to make it to the spd 🤔
put the wires to the pv + and - and ground, and that should protect my battery's also/ CORRECT? thanks Mine is an off grid system with no AC coming in.
The Midnight Solar instructions clearly state to avoid any bends in the wiring, yet you essentially created a 180 degree bend by using a wire nut on your ground.
Unnecessary bends, not all bends. And sharp bends. Don't kink the wires. The actual text from the MS instructions is: "The conductors used to connect the SPD to the line or bus shall not be any longer than necessary and shall avoid unnecessary bends."
Seem pretty silly to have a 1000V 400A breaker from you PV feed. Some very long series strings of panels could possibly add up to 1000V, but it takes a hell of a charge controller to handle that. And never will you ever see anywhere near 400A coming in. You should always do breakers that fit your system. Not so sure I trust this guys info.

Breaker would never trip, it's not even designed to withstand thousands of volts
Thanks for sharing this simple explanation of installing a SPD.
Nice and easy, thanks for sharing/showing this.
This was an easy install. With 6kw of solar the off grid battery has not dropped below 65% in 45 days.
QUESTION: Do you have a link on where to purchase the DC breaker and the breaker box?
QUESTION 2:
Do you tie the ground wire from the solar array to the inverter room ground, and any other details would be great?
thx

I INSTALLED THEM AROUND 8 YEARS AGO NOW I TRY TO KNOW WICH MODELS ARE?

inspection failed 2 wires under 1 lug
