Charging Batteries with generator problems - suggestions?

What is the model number of your inverter ?
What is the connection between the generator and the inverter ?  Please provide both wire size and length.
Where are you measuring the 26 volts ?

 hi guys,

  eric, i'm not sure we understand your ac wiring to the fx2024. did you say it's hard wired with 220vac from the generator plug? or are you just trying to use one leg of that 220 line for the inverters 110ac input? or could it be the fx2024/et model which needs 230vac input? sounds weird..sorry to ask more questions. is this the same cord you were using and the same hard wire setup to inverter input as before the generator was repaired? it seems like perhaps one of the legs of that 220vac gen output was down before the new motor was installed (only giving 110vac) and now it's back working again and trying to feed the 2024 with 220vac? did they even make the fx2024 with a 220vac input? as far as i can tell we want to go from the genset to the inverter with a standard three prong 110vac cord hardwired into the inverter 110vac input.
 
 sorry if this all sounds like crazy talk, but i don't know what else to think.

 we have to recheck our generator output and the inverter input.

 interesting.

I have similar situation; my Kohler 12RES propane air cooled took a dive and I replaced it with a Generac 15KW.  I am feeding the inverter with 240V line from Genset. However, my breaker soon trips. 

Query: should I use the 110 volt line, 30 amp instead.

System: 28 kyoceras
2 OUTBACK inverters VFX3648, 3.6 kW, 120 VAC,
2 mx charge controllers
240 splitter for well pump

since the inverter is 120 vac, seems logical I should be using 120 to feed same even though my well pump requires 240.

thanks for the put down, but I spent 2600 for my new genset. and have solved the problem by using the 50 amp port. you have not qualified cheaper gensets in your post. do you care to qualify or are you more interested in putting someone down..

Please enlighten the rest of us and tell us what make, model, fuel type and KW capacity your generator is...that is if you even have one...more than likely you are on grid.

#1no knowledge, bec. my solar installer configured system with previous genset.

#2 either 120 or 240 for loads up to 12KW and surge to 15KW

both inverters show charge yellow light on when genset running at max.  will not charge with genset in slow rpm and shows a red flashing light.

with no substantial house load, eg pool pump, well pump, washer, 1.5 kw water heater...19 gal., genset will start to vary speed and sound ever so slightly, once the load is removed.

the rest, see #1;

I can see I have a lot of learning to do. Wish I knew more about it. 

We are starting our annual winter rains in So. AZ just now so am using genset more often now to keep batts above 80 percent charge due to extreme cloud cover. Yesterday at peak solar gen. time, system would only gen. 500 watts...this is from a 3.6kw solar system.

They are forecasting an inch of rain here so at least my panels will get a good washing.  Dust cover on panels will impede the solar gen. up to 50% in my 4 years experience on solar only.

whatever, dude
