Re: Current drops when switching from generator to batteries

This is common with gens that have their own built in cool down timer, The FX cuts AUX then drops the AC input but as it still "sees" incoming AC it reconnects after a short delay,,,, and then the gen stops, Giving low voltage/HZ error which is actually what is doing the switching, Unfortunately by ...

Re: Genset Selecton

Go to inverter 1 in hub port 1 for your aux, AGS etc gen start, as I mentioned, can not remember why, Maybe 8 years ago, but using FNDC relay was a problem

Re: Genset Selecton

You need to get the hydrometer out and read SGs for a true indication of charge. Also remember there are 3 volt start settings, 2 min, 2 hr & 24 hr, I put them 0.4v apart on a 48v system, I can not remember what my usual settings were, but something like 2min 47.6v, 2hr 48v, 24hr 48,4v to give about...

Re: Generator battery questions.

Depends on what you want to spend, A maintainer type battery charger is good but expensive (Well not quite as good as they say on the box) otherwise an "el cheepo" battery charger and a timeswitch giving the gen "a couple of hours a week" is my prefered option,

May be worth swapping the controllers round on the shunts ( looks reasonably easy ?) See if the problem "follows" the controller or is it pre ?

Re: Trying to help a mate

A quick google says they are FLAs ? So you need to get a hydrometer to check SGs for a real state of battery charge, Looking at your lower picture you are only getting 1 hr of absorb, Which I suspect is because system has been left at default settings ? That would mean you are only getting one hour ...

Re: 12v Solar Array vs 24v ..

I think your settings are not far off (Could go a little higher on absorb voltage) I believe what we are seeing here is your batteries are VERY low, Nothing above shows you have even reached your absorb voltage, Which you would expect to see for 3 or more hours "on a good day" I guess that may be du...

Re: NC200 load voltage

Unsure as to what you mean by "charge voltage"; I'm under the impression that isnt specifically set, that the charge controller determines the voltage depending on the charge stage. Is that an incorrect assumption? No you have to set it "absorb voltage" from the manual "Absorb Charging Voltage 2.4 ...

Re: NC200 load voltage

What are you using to control charge ? voltage and time or SOC from your battery monitor ?

But to start, Your charge voltage is too low and your absorb time too short, refer to manuals for correct settings.

Where in the world and what do you want to use it for ? EG 60hz & 230v is often the "norm" in parts of Asia, Apart from motors will run a little slower, most other things do not care ?

It seems to me that you have "el chepo" inverter and you are trying to blame you present fault on something that is pretty much industry standard ( if you have decent equipment,,, Not the first time I have read similar "problems") ?

Re: generator

Firstly do not trust ANY battery monitor, They are only as good as they are set up and WILL drift over time, They should be recalibrated to SGs often, SGs are the only real way of knowing your battery state of charge, I equalized my batteries occasionally. I also have a hydrometer and took readings ...

What are your absorb voltages and times ? Do you have temp compensation and what are your daytime loads ? It seems to me that you may already have enough incoming PV but it is possibly not optimised for its best ?

Re: I need an Alternative to PSDC for DC overcurrent protect

yes you can but you will need a little larger fuse, eg your inverter is 2000w at 12v , so 166amps at that, with the surge potential of these inverters, 200a would probably be a minimum,
