Inverter that works well with Generator

[Bossman253]

I have my Deye 12kw 3phase inverter, it has possibility to connect another 1phase inverter to pass AC to it.

Why ?, i will want to connect to 1phase inverter to my 1 phase generator. Or i can connect second battery bank to it, that way i am passing this two or one thru Deye with no-void of warranty. Using such tool as CV connecting it at main battery bank which is connected to deye, will void warranty if something happens.

Can you tell me what Inverter for about 350-400 usd, will be best?.
EASUN 6kw ?

One Generator is with inverter
Second is without,
Both are 220v

Anyone ?

Sorry, I kinda passed over this one, because I really didn't understand.

it has possibility to connect another 1phase inverter to pass AC to it.

I'm not sure how this is possible.

Using such tool as CV connecting it at main battery bank which is connected to deye, will void warranty if something happens.

That depends on what happens.
If any 3rd party product causes damage, it will probably void the warranty.
But what damage could it cause?

There is other things in this world to worry about.
A Chargeverter connected to your batteries are not.
I am running 2 and have 3 Deyes. No issues.
I dont see that it becomes an issue. Ever.

LydMekk, can we talk pm?

I have lost track of how many times and how many people have told you that adding a battery charger to a system does not cause any problems and will not void your warranty. I honestly don’t know what else you want. Rather than take our word for it, or take their word for it, you should understand the system, and how things work and make your own decision about electricity.

Right, sorry for being so borring for you, mate. I am just trying to get all kind of viewpoints and solutions and then choose the right one for me. I am at begining with that adventure i dont want to break anything.

ps. I dont want to overcharge also anything.

The big issues with a generator direct input to the "Grid" or "Generator" input of an inverter are:
1: Most generators are underpowered. Most manufacturers want a generator that is twice the power rating of the inverter.
2: Most generator outputs have higher than normal (acceptable) total harmonic distortion (THD) and the output is not "Clean" enough.
3: Most generators do not respond fast enough to changes in load.
4: Most generators have poor voltage and frequency regulation which vary as loads vary.
5: If for example most inverters when trying to maintain it's AC output in phase and frequency to the generator input will have issues.

A generator powering a battery charger such as the EG4 Chargeverter overcomes these issues and the EG4 Chargeverter connected directly to the battery stack provides clean DC power to charge the batteries and/or also power the inverter while charging the batteries.

The EG4 Chargeverter can provide up to 100 amps of clean DC when powered from a 220-240vac input.

So set your CV output to 55V and you're good. It won't fully charge to 100%, but you don't want long drawn-out taper charge while burning generator fuel anyway. As soon as the current starts to drop, shut the generator down.

Post hurricane Helene. I lost power for three days. I do not yet have a PV array although I have twelve 550 watt PERC split cell panels that are not installed. I ran the house (HVAC breaker open) on my inverter as if it were a generator. I had both of my EG4 CV set at 55vdc and 45 amps. I only had to run the generator for 4 to 6 hours per day (if I did a load of laundry and used the dryer) to fully charge my 12 batteries. I had to limit the CV's to 45 amps as one of my 240vac 30 amp generator breakers would trip at 24 amps. could not get 6000 watts (or the full 7200 watts) out of this 25 year old Chicago Electric 10kw generator (just got the replacement breakers delivered). I could monitor all batteries and the charge process on my computer. I could also monitor the Victron shunt and the inverter. All worked well and as long as i had about 4 gallons of gas per day I was fine. I was prepared to place the PV panels on the ground in the back yard and hook them up if I had too. the CV 55vdc output would get a number of cells in my batteries to 3.5vdc where cell balancing started and the SOC would reset to 100%, the amps would also drop as the batteries charged to 54.0vdc and a bit higher. The CV and my generator worked very well.

What viewpoint do you want to hear that you haven't? You want someone to agree with Deye? OK. I agree with Deye. Does that make you happy? Buy a 3-phase generator, and be done with it.

Like i said, there are couple viewpoints and much info that i already got from my questions, each answer got more cents to my question and now i have better understanding for system
How it works, and this post gave me and others more info for gen topic. For that i am grateful, for your help also.

As to your last talk, got already idea what i need to do. No need to agree or disagree, better ask two times than be sorry later.

My final thouthts are that there are atleast 4 ways of doing what i need, one of the best but not cheapest is CV which came today.
