Use a heat pad powered from the generator and insulate your tanks after as long as you start with 2 full 40lb tanks you shouldn’t have any trouble. We had a situation years ago where we had to heat a space for 2 hours with a 60,000 btu furnace. In -20 Fahrenheit temperatures. I would set a 20...

I am not an overlander but we do boondock most of the summer in the north east USA. My thought would be to do both.

I went to 48 volt and left my 12v system and battery and in place recharging the battery whenever the inverter is on. I like the redundancy I get with having a 12 volt system that still works if I exhaust the 48v system. There are efficiency losses this way but it has been worth multiple times...

I use 2 diesel heaters in my traavel trailer I was able to put a 15 gallon tank between the skirt of the trailer and the frame. A diesel heater takes up almost no room at all. You could probably do the heater thing and add an extra bunk or fantastic set of 30” dresser drawers.

How are your solar panels configured? What voltage do they output to your pwm controller. Pwm doesn’t work well unless you’re getting voltage in just the right range. What voltage are your batteries reaching with solar? What amperage is going into the pwm? Does the unit tell you how many amps...

Could you explain a little bit more. What batteries are you using. What’s your budget. What are you powering with the inverter. What are your future plans. Any of these factors could affect what inverter is preferable or cos effective. Most people don’t move to 48v for 2000 watts unless the have...

Your source for grounding information is relevant to higher voltage ac current. Most of the purpose for grounding is irrelevant to a 12v system. Millions of 12v electrical systems are in use every day that are not earth grounded in automotive and truck applications. Most of these systems employ...

do you have any slides or levelers? These often require substantial amperage to operate.

Yes we live near the Canadian border and we have noticed that -40 is a peacemaking temperature the US and Canada agree on what temperature it is, the Ferrell cats, dogs and other wild animals sleep together, nobody hogs the outhouse. and you hear very few arguments outside.

We routinely get -30 I didn’t remove mine just charged them up and disconnected them

Check the temperature in that location idling with the engine fully warmed up and facing the sun (similar to the conditions you will get stuck in traffic)

I live in an area where temperatures routinely drop below-20. Never had a breakaway battery last much more than a year. If the battery that runs the breakaway runs the tounge jack you have tested the breakaway battery every time you connect. I have no choice on my flat bed with a crank jack but...

I put in a 48v AIO. Out ac needs would really push the envelope of a 12v system. Instead of using a buck converter I left the entire 12v system in place. I love the redundancy. No ac loads that I have are absolutely necessary. If I didn’t have such simultaneous high use of ac current on a...

2/0 sounds about right for the inverter. 2000 watts at 12 volts is a lot of amps.

You will have losses between the charge controller and the inverter even with a aoi unit.

I would recommend testing to make sure your proposed location doesn’t get too hot. Engine compartment temperatures can get astoundingly high. I’d stick a remote thermometer inside your battery spot and see what temperature you get. High temperature will drastically reduce the lifespan of your...

All 4 are possible 1 is done with a charge controller 2 and 4 can be done with a victron multiplus. 3 is the most difficult and the solution varies a lot depending upon how much amperage you want.

The voltage your panels can put out varies by temperature of your panels. You need to avoid the 150 volts at the coldest temperature your panels will see. You must have less than the max voltage in full sun with no load.

You probably could but wow that would be pricey. I put 3300 watts of used commercial panels on my camper for just over $700.

The solar panels you listed only produce 37 volts. The charge controller requires a minimum of 120 volts

I’m just seeing this post you may have already sorted this out. My question is what “ground” are you referring to? Grounding the case of the inverter, the ac output, or the negative battery cable to the inverter?

Does the breaker trip instantly when the power returns or does it take a little time?

I have not done a capacity test recently we are using the system continuously right now and it would be rather inconvenient. The device he sent me was a passive balancer that connects to the bms.

I use 5 of these batteries, 4 in series in a 48 volt system, and a 5th for the 12volt side of an RV. I have used these pretty steady for a few years. The seller supplied me with passive balancers for each battery and they tested at near capacity once balanced. I would not recommend them as their...

The answer is it depends on your situation. The shape of your roof your budget and a bunch of other variables. No one size works best for all setups.

Sorry to hear about your Neighbor issues. If it makes you feel better you could swap out the 60 for a 30, I doubt that a inspector is going to be very concerned about that if he wants it changed he will add it to the list of the other things you had never thought of that he wants done to...

The 30 amp inverter breaker should cover the wire no problem and the 60 amp breaker is simply a switch. I wouldn’t bother changing it

What size wire runs from your inverter to the panel?

your layout is extremely simple. in your situation you do not need a fuse between the solar panel and the controller. A simple automotive style 20 amp fuse should work between the controller and the battery as close to the battery as you can get to the battery. If you want to add more solar...

10/2 Romex is solid copper it doesn’t always work well in vibration prone areas and doesn’t terminate well with standard solar connectors.

I only use fuses on the end of each series string of I have more than 2 strings in parallel to protect against fire in the event of the catastrophic failure of a solar panel. I don’t use any connections or fuses that are not necessary as every connection is an additional failure point and...

If you are renting and this setup came with the place. Technically it is your landlord’s responsibility. From what I am seeing it looks like the system is not fused properly or wired correctly. You obviously already have performance issues. Your landlord may have inherited this problem. You need...

I think the voltage is to low to charge unless you have full sun if you wire in parallel. Series configuration is probably best in your situation.

Your question is very broad. To narrow it down you need to be reasonably specific on what you intend to power off of your 120 volt side otherwise the options and possible combination of components is so wide that few will be willing or able to spend the time to list them all.
