Re: The case for multiple small inverters

This sounds like the right compromise. Thanks!

Re: The case for multiple small inverters

That’s right!!

I knew I was getting this idea from somewhere. It was in the inaccessible back corners of my mind.

So being able to hit the peak efficiency AND being able to turn it off when...

Re: The case for multiple small inverters

What about a single inverter with fancy battery wiring?

Is it an improvement in efficiency to wire the inverter to the battery bank in such a way as to have it see 24v or 48v on the supply side?

Re: The case for multiple small inverters

Yes, this was the only logical installation method I was thinking of.

Re: The case for multiple small inverters

I suppose an analog thermostat would work best for this.

Regular refrigerator thermostat set to enable the refrigerator compressor at 40F, mechanical thermostat set to enable inverter at 39F.

Re: The case for multiple small inverters

This interests me a lot.

I’d rather store some of the excess solar energy produced during the day in an arrangement like this instead of in lead based batteries.

Does the food in your...

Re: The case for multiple small inverters

Yeah, the washing machine is not on my want list at all. I’ve advocated to have it installed last after we are aboard to see if we really want it. Every pound does indeed count.

I’m not...

Re: The case for multiple small inverters

We all make our choices and compromises.

A lacking galley is not one I’m putting up with. A 50’ cat with a 70ft air draft, currently weighing around 12,000-14,000lbs,, props that retract out of...

Re: The case for multiple small inverters

I feel like this is where I’m probably headed given the reality of the situation.

I was hoping to squeak out a little more electrical efficiency, but in reality, the electronics you’re talking...

Re: The case for multiple small inverters

the thread is about selecting either one large inverter or multiple small ones to power given loads. In the case if refrigeration, a cyclical load. In the case if everything else, user controlled...

Re: The case for multiple small inverters

Ok. Thanks. I was definitely misreading that.

In my defense, it’s nearly impossible to see the full width of pictures on the forum on my phone. They get cut off.

Re: The case for multiple small inverters

Well, that kills my theory.

Thanks for the recent real life experience data point.

If I can find the right big one, maybe that’s the best way. Checking out the Mastervolt.

Still, some of...

Re: The case for multiple small inverters

Well, no. I definitely don’t need to be powering microwave clocks. That was just something a different poster said I responded to.

The home refrigerators have too much going for them to even...

Re: The case for multiple small inverters

Where are you getting 15 watts?

I see 36 watts as the absolute lowest the 2kva unit uses when it’s completely off and looking for current to turn on.

Next level is AES mode and that’s 7 amps...

Re: The case for multiple small inverters

Ok, what inverter is this, so I can compare?

Edit: found it. It’s the victory 2kva.

Re: The case for multiple small inverters

I don’t think this is right.

Inverters are sold based on their continuous output oddly enough. Most can handle near double their rating for brief intervals like the LRA of a compressor.

So a...

Re: The case for multiple small inverters

I guess what I’m looking at is having the ability to scale the inverter(s) for more efficiency. Bringing them online when needed. Shutting them off completely when not needed.

Not possible...

The case for multiple small inverters

I had been looking at getting a big inverter (3kw) to run a refrigerator, chest freezer and whatever else, including microwave, dishwasher, washing machine.

The more I have looked into this, the...
