Maybe $350 ish? Basically just this guy or 2 and some wires https://www.amazon.com/Vmaxtanks-Vmaxslr125-rechargeable-Solar-Inverters/dp/B00ACNO2AO/ref=redir_mobile_desktop?_encoding=UTF8&psc=1&ref=yo_pop_mb_pd_title

be careful to wire everything properly safely, ground, and add fuses for safety. Too many safety measures is the perfect amount.

I assume you are on a tight budget, but if you can come up with a little extra you will be much better off with this battery.

Also, a pure sine wave inverter will be far better for powering/charging sensitive electronics.

For an additional $250 or so, you'll have a battery and inverter that will both last years if used properly.

ps4 is about 200w gaming and has pretty high idle consumption of 50w so disconnect when not in use. Add in the power usage from your TV (Let's say 100w which is overkill). Your laptop drawing 13A? That seems too high, no laptop draws 1500w. my high end laptop draws 170w. 1500w is a really big gaming computer with dual gpus.

I'd estimate ps4, tv, and laptop power usage at 400w (overestimated a bit) if you wanted to do that 6 hours a day that is 2,400kwh. I've read you shouldn't discharge a battery below 50% so cut any ratings in half.
This battery is good for 750 watt-hours

For your whole setup you would need 3.2, maybe 3 of those batteries.

Take this with a grain of salt, I'm good with power calculations, but don't have too much knowledge of solar system design.

I have one of these installed in my rig and its fantastic. It currently lives under the bench seat. If you are adding a second battery to an already existing auxillary battery setup be aware that the current life of your battery now can affect your new battery. Basically batteries need to be installed in the same condition (ideally new) or they can screw each other up. If you're just adding a new Aux battery that will be isolated from the starter battery you should be good.

I did a project about 3 years ago for an emergency lighting system. None of those dinky plug-in units that will barely light your feet as you walk past. No this thing lights up the whole house using those long 5-meter 12V LED strips you find on eBay. And it will output high brightness for well over 24hrs, though never tested that long. Longest outage so far was 1/2 day.

I got a 125AH deep-cycle marine battery:

A smart charger:

A 12V automotive relay (to switch to battery on power outage), some 12V LED strips, wires, panel-mount volt/ammeters. The system's been running fine for 3 years.

Absolutely!

Another issue is that might be the constant draw but with a peak amp usage of 30 amps when the compressor is first kicking in and what not. I know there's a few solar subreddits, I'll see what they have to say.


Edit:

Not the same model, but a similar fridgeaire being talked about. Looks like they don't list starting amps/watts on their page, so that 4.5 amps is probably closer to 12 or 13a during startup.

>So the "low-voltage start-up" on the Frigidaire units is a timer delaying compressor starting until the fan is up to speed.

>The RV "hard start" mod adds an additional capacitor, and usually that capacitor has a timer to delay firing - which achieves both easier compressor starting AND compressor delayed starting.





So with all that I think expect a draw of 1500 watts/13A at startup..... which still seems lower than I would expect. Everyone says you need a crazy large system to handle AC and I'm starting to think a 4000 watt inverter. 2 high efficiency panels and a couple 125a AGM batteries could handle it (albeit for short bursts of 10-20 minutes and understanding it'll have a recharge rate of 3-5x longer than the AC usage.)

What am I missing? This seems too easy.. if it was wouldn't everybody be doing it?

Yes that's a way you can do it, but imagine that you're camping and you totally depleted your deep cycle battery, and now you have an empty battery and a good battery, as soon as you turn your key (even before the engine is running) both batteries will be connected in parallel. If you try to start your car you'll find that you cant since the good battery is essentially charging the bad battery, if you keep trying start your car you'll soon find the the voltage of both batteries is 6v. If you find yourself in this situation you will have to manually unplug the depleted battery to be able to start the car. This scenario is exactly what the power stream is meant to prevent since it will not connect both batteries unless the alternator is outputting 13.4v.



Yeah I guess for your application the Goal Zero is the way to go. That's why I Initially just mentioned an extra battery with a cheap inverter hooked to it, and charge it whenever you come home. If you want to charge it while on the road just take the leads of a cigarette lighter plug and connect them directly to the extra battery to charge it, it'll be a slow charge (5~10Amps) but that's exactly how the Yeti Goal Zero does it. But if you have the $600 to spend on the yeti, go ahead.
