Re: My charging settings

My hydrometer is not the greatest. It only cost 25$ but the readings are all in the 1.270s at a temp of 68 deg. Do not worry too much about the "numbers" it is what they are doing is important, eg not rising any more, bat is full, If you know what the particular cells "normally" reache when full an...

Re: My charging settings

Your settings look a "reasonable" starting place (Apart from auto EQ, I prefer that done manually) Have you got an Hydrometer and are reading SGs ? They are the gold standard for setting up your bank properly,

Re: Aging batteries trying to charge with ac input line

You have treated your present batteries pretty badly, Low on water (the biggest NO in the battery book) No EQ and by leaving system at defaults,,,, Chronic undercharging (defaults are way to safe, "out the box" especially only 1 hour of absorb time) Your SGs will be all over the place and battery ef...

Re: GEN STAT over LAN

You extra inverter "should" give you enough to start it but for future reference have a look at VFDs, https://en.wikipedia.org/wiki/Variable-frequency_drive That would give you soft start and variable speed up to 110%, They can save a significant amount of power just by backing the pump down a littl...

Re: GEN STAT over LAN

How often does your gen run anyway ? (without additional pump run time) If reasonably often you could wire the pump straight to gen output, so when gen runs pump does if required (controlled by float switches) May also be a good idea with your present setup as a fail-safe,

Re: AGS not working - help with AGS config troubleshooting

I have the 2 minute voltage set at 44.4v
Thats very low,
At 45.2v, that only lets the batteries drop to 81% SOC.
I suggest you confirm that with a hydrometer, As above thats a very low battery voltage for 81% SOC,

Re: FM80 on Two Battery Banks Configuration

Have you altered the FM from defaults at all ? Refer to battery manual for settings, But if not, By default you have a 1 hr absorb time which is WAY to short and Charge voltage also is low, around 4 to 5 hrs would be a better starting place then calibrate with a hydrometer, Voltage, again, Manual, Tim

Re: wiring generator to inverter without using AGS

You also may want to put your absorb time right up , Float charging with a generator is a total waste of fuel, So if you do "forget" to turn it off, at least it is doing some good :grin:

The best battery monitor you can get would be a hydrometer :grin: Forget about all the electronic ones, They are ALL only as good as they are setup and will drift over time which will have you constantly re-calibrating it with a hydrometer anyway, #-o

do you have schematic for the generator alternator ? depending on its type (needs to be 12 wire) It could be reconfigured for 1ph, you would get about 58% of 3ph rating,

Re: adding charge amps

Looks like it would be irrevelant once the batterys got over the 13.8.
Yes you are correct, Maybe help with the early part of bulk but you want 14.4 minimum realistically,

Re: Solar system on a 40 ft Catamaran

Another thought, The FMs default setting are very safe (too safe, 1 hr absorb is way too short) Refer to manufactures specs but 4 hrs is a more reasonable time, Absorb voltage, again, by the book,

Re: Solar system on a 40 ft Catamaran

As above but to add, The FMs remote battery temp sensor is very important, It should be placed wherever the warmest part of bank will be,
Also a suggestion, Depending on how much you motor, It may be worth while putting a smart voltage regulator on engine alternator,
