Update: I replaced the questionable breakers with Gloso breakers that are similar to the Blue Sea Systems breakers and AIC rated. Currently testing my 12v outlet to a portable fridgeFreezer I tested earlier with the inverter. On battery it seems my run time slight more than 2 days give or...

@Bud Martin - since the system is always connected and I have the breakers and cutoff switch I have not seen any sparks or heard any noise when switching the disconnects or breakers. If there were sparks they must have been internal to the breaker or swtich. I hate the screw type terminals...

@sunshine_eggo - You have enlightened me! These are not AIC rated and have very little info at all on there rating other than the general rating. I looked at Blue Sea and I think the 285 would work it’s just a much smaller lug size and oddball configuration. Also expensive for two I need...

@42OhmsPA @sunshine_eggo - Duhh now I see what you're referring to the 60/125amp round breakers. They had really good reviews. Didn't see anything negative. What is the problem with these types of breakers?

The mppt is a Renogy Rover not sure why you thought it was Victron? I only have the one breaker showing and that’s just for the 120v a/c outlets. Not sure what would be wrong with it? As far as I understand the pre charge wasn’t needed and no damage occurred from the capacitors charging...

I’ve got this at about 85% complete. This is all installed inside a Dewalt Tough Chest 38 in. 63 Gal. Mobile Tool Box. I’m using a 12v 200ah Ampere Time LifePo4, 1200w Victron Phoenix Inverter, Renogy Rover 60amp MPPT, and a Victron BMV-712 shunt/monitor. There’s 2 low power quiet fans...

So essentially Wong it after doing extensive research and viewing conflicting information?

Ahhhhh ok I see now I read the wrong terminal size. So 2 awg has a range of 75-100 depending on insulation rating and heat etc.. so if the actual unit only puts out 900 continuous watts as someone stated above that would be a 100amp fuse needed and using 2awg is marginal at best?

Strange that ampacity rating are widely different for the same wire size. So yes 4awg is 21mm but 3awg is 26mm so 4awg is max if using the wire only. Those connectors you show theoretically could carry more current at the tip since they’re solid. But why would Victron undersized the...

I’m connecting a 12/1200 Phoenix inverter and after much research I’m still unsure of what fuse/wire size to use with this. The terminals only allow for a max of 25mm size cable which translates to 4awg. This seems to small of a gauge for a 1200 watt inverter that could pull 100amps. 4awg...

They’re specific to their devices and their mobile system discussed still has the possibility of being connected to a/c for supply and earth ground in a panel. Unless I misunderstood. The Phoenix Inverter is very different from their system also.

The power box is 100% off grid unless I need to recharge without solar and have to use the home A/C. The inverter is factory set to floating ground and I’ve left it that way so far woth no ground wire attached. If I charge the batteries the inverter would be shut off and the battery positive...

Your correct on the A/C charge. But since when charging with A/C I would isolate the battery from the inverter with a disconnect switch. But also since not an RV type setup I’d never be using the system while charging

Interesting but yet not the right info for a Victron Phoenix in a off grid standalone situation. They were always tying to grid or a fixed ground in all 3 scenarios. At home I could run a wire to my home ground rod or a AC outlet ground and thus be earth grounded. Or I invent a floating...

So with the risk of shock on a floting ground system such as with gas generators or solar or battery systems like this you’d think there was a safety device that’s a available to offer better protection other than GFCI? Maybe an ARC fault breaker on the output of the inverter? Anyway much...

There seems to be a lot of contradictory info on this and very little help from the manufacturers. I would assume since this is acting like a generator so to speak it would simply be a floating ground and yes I would take the ground lug of the inverter to the metal frame and any other devices...

I’m building a mobile power box with a 200ah LifePo4, Victron Phoenix 1200 Inverter, and a Renogy 60am MPPT. The goal is to charge either via solar or a/c. My question is related to proper grounding. With this being mobile I’m assuming I leave the inverter wired as a floating Neutral as it...
