In line fuses work just fine.

This is false information. An evaporator doesn't cost more than a whole system.

With no shore power connected, where is your neutral connected to ground? Inverter? Where is your ground bonded to the chassis? Nowhere?

Incorrect. A garage should be sealed from the conditioned space of a house to be up to code. If it is not, then that should be fixed before you do any other upgrades to a house. Also, a fresh air intake (makeup air) should be added to the evaporator in order keep from getting negative pressure...

LG has branch ducts on their smaller ceiling cassette units, so you can run vents to closets and bathrooms, and allow more units per condenser than most of the other brands. The only brand that beats LG is Mitsubishi, and those things might as well be made of platinum, because they are...

A combiner box is easy, but where would you put it? If you put it inside, then you need 6 wires going through the roof. Something to think about. The only part of the "ground" that is misleading is the very definition of "ground" "ground or earth may be a reference point in an electrical...

This is incorrect. If the inverter is bonded (neutral to ground) at the inverter, and you ground the inverter to the chassis, then you will always have a bond on the vehicle. You shall never connect the neutral to ground in any way, except at either a neutral disconnect (which is uncommon in...

No one said anything about adding return air from the garage, EVER, so quit mentioning it. There is nothing in any code I am aware of that prohibits a supply duct from being placed in a garage. There is specific prohibitions for return ducts only. To the OP, a better way to install horizontal...

Rusty, I already answered your comment, but I'll explain it again. No one is stupid enough to add a return duct from their garage to the rest of the house, but there is nothing in the code preventing the AC in the garage from being part of the main house AC. You can add a duct, with no return...

Code says you can NOT return garage air into the house, because of deadly gasses, but there is absolutely nothing in the code anywhere that I'm aware of that prohibits you from using the same ground water loop or adding a split system to your main unit. The CORRECT way to condition a separate...

If I were building a new home, I would go with LG Multisplit for heating and cooling, closed cell foam in the exterior walls and floor joists between levels, sound rock in interior walls, and no geothermal. A simple solar setup is cheaper and will cover all your energy needs. I also like hybrid...

Why would local code prevent you from putting an AC in your garage that is part of the other system? I have never heard of such a thing. If you are doing geothermal for the rest, then I would add a unit to the garage that uses the same piping system.

Victron units use so little power that the eco mode is not worth it in most cases. A simple small portable solar panel can offset the consumption from a Victron.

You're not far off track, but you need to remember one thing: fuse for wire limitations, not load limitations. You aren't protecting the load, you are protecting the circuit. Max fuse size on 10ga is 20a. 8ga can go to 30a, but 25a is better. If you have 10ga anywhere in a circuit, then the...

The chassis ground is not a neutral bond, it is a DC bond. It should be connected to the frame of the RV, or a DC bond (wherever you can get it from)

Seriously? You really expect people to take you seriously when you say things like "I don't see any off grid systems with a meter"??? I didn't miss any point of any system. In fact, I KNOW you missed some details, making your statement even more ignorant. In many areas of the USA, it is illegal...

Personally, I would start with one battery around 300ah and see how much more you need after running it for a couple weeks. As others have mentioned, battery size needs are wildly different for every household. You may find that one battery does enough for you, and just supplement the rest with...

I would get the Multiplus 2 3000, and put a solar panel on the roof with a small charge controller and never turn the thing off, even though the Victron inverter/chargers save their settings. The Victron stuff uses very little power when idle, so a simple solar panel would keep it from draining...

What you have done now is create 3 bonds, not one. That is wrong. If shore power is connected, then you will have 2 neutral bonds active, which is wrong. If generator is connected, you'll have 2 neutral bonds active, which is wrong. You can ONLY have neutral bonded at one location, the power...

I think everyone is WAY overthinking this whole thing. If it were mine, I would put a transfer switch after the meter. Connect everything up to the transfer switch, and just turn off any large loads manually that I didn't want to run on the inverters (if there were any). If you have enough...

If you don't need the AC-IN2, then the MP2 is cheaper and does everything else. My issue comes down to the need for Split Phase. The MP2 doesn't come in 10k 120v, so for split phase, you would need dual parallel 5k MP2s. The wiring is a bit more complicated, but the 4 5k units are nearly the...

I normally run float at 13.6v and bulk anywhere from 14v-14.4v, depending on application. Lifepo4 is essentially full at 13.4v. The tiny bit you get by charging to 100% from 99% isn't worth the risk of bloating the cells with all the extra voltage in my experience. Unless you need every last...

Neutral bond should be at the power source, so when you're on shore power, you'll have a floating neutral in the rv. When you are on Inverter, you'll have a bonded neutral. If you run on a generator, then you should run a bonded neutral generator.

"Constant motion of a sailboat" I don't know what kind of sailing you do, but I try to keep the keel in the water. I have been in some really nasty shit sailing, and never experienced enough un and down motion to dislodge any batteries. Use a thick closed cell foam damper under the cells and...

Everywhere around me sells the Smartplug, so I don't know what your issue is with obtaining one. Also, why don't you just stop losing shit? I have been in the business for many years and almost always, I see the original cables and adapters on RVs and Boats. Very rarely do we ever sell...

My recommendation is to use the Smart Plug. Basically everything we install now on boats are Smart Plugs. The only down side is they don't make a 50a single leg version, but that isn't a common need anyway. If you need 30a single leg service, then get the 30a plug, plus a 30a to 15a 4' adapter...

I have done a few installs with LITime (Ampere Time) batteries, and even more with Life Blue batteries with zero issues, but on all our trolling motor installs on boats, we use Abyss batteries exclusively. I am currently doing a 30kwh system with 4 5k quattros on a 65' Donzi, and using LI Time...

There are calculators online that show you how to mount actuators to allow for a certain tilt angle, and most importantly, show you the force required, based on weight. The only advice I can give you from my experience is to attach the top of the actuator away from the hinge. This requires less...

You could use a linear actuator to lift the panels, then you wouldn't need to lift them by hand. Also, you could use linked linear actuators to lift multiple panels simultaneously with multiple actuators. You will have to allow for a little space under the panels for the actuators to sit, but...

Well, I can only run one machine at a time, so there is no need or reason to start more than one plus the dust collector at once. Also, the AC is a soft start inverter type that doesn't have a significant startup draw. All of these machines currently run on a 5kw generator without issue, so I'm...

I'm looking at buying some 540w Vikram solar panels and would like to know if anyone knows anything about them.

Well...I won't have to worry about any of that, as this will be a mobile installation in a cargo trailer. I'll have a 240v AC, a 240v Dust collector, and a 240v Tablesaw connected, so those won't need balancing. The 120v side will be limited to things such as Planer, Miter Saw, Jointer, etc...

Don't connect the Alternator to the lithium, unless you plan on letting the magic smoke out. Lol The Balmar regulator can be made to safely connect to an alternator, so if you connect it properly, then it will prevent damage, but I would just use a dc-dc to charge the lithium. Also, most...

Is load balancing necessary? If I don't have to spend the 600 bucks for the transformer, I'd like to use that money for something else that is needed, but if I need it, then I'll get one.

Hello all. I have been scouring the threads for weeks but can't seem to find any thoughts or recommendations on the Victron Autotransformer use in split phase setups using multiple inverters. I'm designing a mobile system to utilize dual Multiplus II 3000/48 inverters in split phase operation...
