Inverters with remote wire

[jrcleveland1990]

Considering using electrodacus bms. However the inverter I planned to used giandel 24v 2000 wat has a momentary switch to it. The one electrodacus recommends is "slightly higher in price" at 3 times the price lol

 

[jrcleveland1990]

What options do some of you guys have

 

[johntaves]

I am going to use the electrodacus bms too. I have a victron multiplus compact 24/2000 which has a position switch for off/charge/invert+charge, which means I cannot control the charge separate from the invert. Which means I will be selling it.

My plan, so far, is to get a mean well RSP-750-27 to do the charging. I expect this will be rarely used, but want a way to bump up the batteries when the weather is lousy. I don't see the need for the fancier inverter/charger features where the shore power is seamlessly blended with the inverter. Since I will have LiFePo, I like the idea of getting a simpler charger that has no lead acid charging logic. I also see no need for any display or control (other than power on/off via BMS) on this lump of metal.

For the inverter, I also want simplicity. I see no reason to have anything displayed or controlled (except remote on/off via the BMS).

1) low idle power consumption
2) quiet
3) I am learning that there are low frequency inverters and high frequency inverters. The low frequency ones cost more and my understanding is that they will be more capable of handling the surge loads from a fridge or AC unit. I expect I will be trying to use the air conditioner and also running my propane/AC fridge, so I want it able to withstand many cycles of load during a day.

I have no freaking clue what to do about the inverter. It seems like the more expensive ones (samlex, victron, magnum) are low frequency, but then have the charging baggage that I assume increases the cost.

Will touts the Giandel (I will go for 24v 3000w), which does seem to have a momentary switch. I would bet it can be rigged to be controlled by the BMS, but if there is nothing special about this unit, then with all the other choices, why not find one that has a positions switch or a more convenient remote?

I will be very succinct here: The Giandel is LOW FRUIT Value Inverter ! The Electrodacus is NOT, It is serious stuff for serious gear.
You are effectivey wanting to build a Corvette but using a 2.0L motor out of a 1978 Chevette !

Giandell's are fine as far as a Lightweight HF Car Inverter and they are good for what they are.

I wanted to go with giandel based on Will's recommendation and Amazon reviews. There are alot of inverter options for the same price range with poor reviews some look like they will instantly catch fire. I have no attachment to using this inverter guys just stating where I'm at in my project. I just wanted to see what some of you guys are using

Not sure if you read the post I have no reason to stick with giandel I'm not running my house with this. I'm just making a small solar project with a mobile battery bank and inverter. I was hoping either get confirmed stories of inverters people have wired up to work or offer some affordable options .you somehow you forgot to offer any of this

I gave up for awhile on looking at inverters. Kinda same thing in a portable setup but dont want to go with something too cheap that I'll have issues with at the wrong times.

Dacian recommended 2000 watt from cotek but the reviews are terrible for almost 700 bucks. Another member reccomended a samlex that I found for under 600 which seems like the right fit. So either pair the samlex with electrodacus and use dssr. Or go with a victron controller with chagery with the solid state relays that are being cooked up in another thread. Price wise there about the same. First time hearing about high and low frequency so I will look into that

Have you looked into the Victron Phoenix?

The low wattage models are relatively cheap for a top tier brand, but when I say low, I mean low (like <800W). I know you are looking at 2kW, so the Phoenix might not be the best option for you.

Highlights are peak efficiency in the low to mid 90's. Low idle consumption and extremely low idle consumption in 'Eco mode', 5 year warranty, remote On/Off switch, models with or without VE.Direct and Bluetooth.

Yes, I wanted more juice than low, and the big ones are expensive. Plus they throw all sorts of features that are unnecessary when you have something like the Electrodacus SBMS0. I don't need any remote control on the inverter, nor any readouts from it. I just need remote on/off. The BMS will tell me how much load I am using and separately how much charge.

It seems like it should be possible to find a low frequency high power inverter for say $600 that eliminates all the fluff I don't need.

Yeah, I agree.

I am also planning to use the SBMS0 and I personally still believe a lot of Victron's "smart" featureset will be valuable. The SBMS0 is great from a system monitoring standpoint (and as a BMS of course). But If I understand correctly its control capabilities are limited to a binary ON/OFF for charge and a binary ON/OFF for discharge.

I see three main benefits of Victron's smart devices in combination with the SBMS0 (and all of them are subjective/based on use-case and priorities)

1. Layered control & protection. I see my BMS as the safety layer of last resort, the least elegant but the most definite solution. This is less true of the SBMS which is more elegant in its implementation than most BMS' but still somewhat true.
2. More granular and precise control beyond simple on/off. I like having the ability to disconnect AC loads separate from DC loads, set different disconnect thresholds, or manually put the inverter in low power mode.
3. I find the Victron Connect app useful, clean, and very intuitive. There are situations where I may want to switch off the inverter but keep DC loads connected (or vice versa) or put the inverter in low power mode, with the Victron connect app I can do that with the flip of a switch in my pocket.

None of these features are necessary and there is definitely some overlap in capabilities, but I really like the ability to monitor and manage the overall system via the SBMS interface, and also manage and monitor individual devices via the Victron Connect app, and really appreciate how intuitive Victron's interface is.

True, I agree that I should look for one that has an adjustable low volt shut off.

I get the appeal of an all victron implementation. Once you throw in the SBMS0, the useful, clean and very intuitive user interface gets more cluttered. I wish all of these vendors would deliver their UI via wifi. They can start up on AP (Access Point) mode, then we get in and change it to use our existing wifi (if it exists). This would enable us to get to any device via any of our computers, tablets, phones, and arduinos that we see fit to use. The browser is the universal user interface.

This is another way of saying, I don't really like the victon solution where it is only great if you stick to their stuff

Oh, well.

Oh, well.

Or possibly better yet, an open source 'frontend' (maybe not the right term) using open communications standards that could exist independently from any one vendor but any vendor could plug into rather than all reinventing the wheel with half assed UIs.

In fact Victron's color control GX operating system "Venus OS" is already open source, I wonder if that would make a good base to build out from if anyone were interested in the project. Its already been adapted to run on the Raspberry Pi. But that is more of a central monitoring hub.

To a large degree that is exactly what the browser and http is. The different UI requirements for each different device can be rendered in the browser and delivered via the ethernet standards without colliding with each other.

The different devices have different UI needs and there is really no commonality between them that would benefit from some even higher level of shared UI functionality.

Developers like me, could easily provide solutions that aggregate the different websites (each device is a website on your LAN) together into a more cohesive UI.

In short, we agree and the answer is ethernet, wifi, http and the browser.

I am tempted to try the "reliable electric" inverter. https://www.amazon.com/dp/B078MPQ382/ref=twister_B07M83DLT5?_encoding=UTF8&th=1 (the amazon ad has "generator" in the title, but that's wrong)

It has a mechanical switch, but that should be easy to hotwire. Here is a video of it in action.

. It seems like it spins up the table saw about as well as my victron multiplus compact 24/2000, so I am betting that my victron is a nice low frequency unit that can deliver more than the 2000watts for a moment, but the reliable one can only deliver the same even though it is rated at 3000w.

It seems nuts to spend a little more than double to get the Multiplus that has the proper remote on/off for the inverter and separately for the charger. Although, I suppose the multiplus will spin up that table saw much better since it's rating of 3000w will be 50% better than my compact multiplus.

I have 2 of those inverters both work great I started with a 2500 watt one and built a cabin with it. I upgraded from that to a 3500 watt one only because I had to let my chop saw get up to speed before making cuts. The 3500 watt inverter solved the problem. I have since upgraded to a Samlex because I wanted some bells and whistles.

I already have chargery and waiting on some of those relays to be cooked up so that should work fine. Some issues on inverters are size and wanted 3k size pure sine wave but will have to make sure it will fit in my case with the batteries.

What model is the Samlex? I assuming the reliable one is a high frequency type and am hoping the Samlex is low frequency. I am hoping I can get some feedback from your experience to confirm or deny my impression that the low frequency units of similar wattage spin up motors faster than the high frequency ones. That info might help to make a better cost comparison.

 

[Steve_S]

EVO's are Low Frequency Inverters, excellent piece of gear.
But then again, I own one now and love it compared to the junk I had before. I can even run my Big Compressor & MIG Welder off it without a blink. NOT that I do that regularly, just had to test it out.... I use a 9kw Genny to run those normally.

It's an Evo 4024. So it produces plenty of power but figure it costs 4 times as much as the wzrlb ones.
