Re: System Setting Issues or Battery Issue?

Blackswan555: Yes, there are battery temp sensors as I requested they be installed and the solar installer charged me for them. I do not think it has anything to do with your missing absorb cycle but for future reference your casita temp sensor is not working, the "255" reading on this "Btmp (readi...

Re: System Setting Issues or Battery Issue?

left the absorb time setting for the time being at 3.0 hours as that is the Concorde recommended setting for their AGMs. Do you think I should still bump it up to 4 hours? You could do, The problem I am seeing from your numbers is that you are not even getting your 3 hrs at the moment with the CCs ...

Re: Is there any danger in plugging in MC cables?

Not night but I always leave one panel per series string disconnected whilst I have my hands "in there", You can still sometimes get a little tingle, But compared to a possible 120v plus DC tingle, it is nothing (120v DC will kill you on a bad day)

Re: System Setting Issues or Battery Issue?

As Sandy says, You seem not to be getting much absorb time, around 4 hrs would be a more reasonable number to see, Check your absorb time setting, Also Amps do seem low, You may want to look at what is being produced mid afternoon on a good Sun day, Batteries fully charged, Go into house and turn so...

Re: SOC doesn't match Load kwhr in Dashboard

You could put some of it down to losses, But 10% seems a bit much, It sounds like your FNDC is still in need of more calibration, (especially if the batteries are reasonably new) What are your SGs vs what the FNDC & Optics are telling you ? Tim To add, I recommend cross referencing/checking FNDC aga...

Re: Batteries Below Full Charge

It will take a few days/cycles to get them back up unless you want to run a grid/gen powered source to give them a boost, Your absorb voltage could also go up to 58.4 for now, That should see some improvement over the next few days,

Re: charge parameters for 450Amp/hr battery bank on VFX3024E

I am not an AGM expert, But a couple of things to keep in mind, You MUST NOT overvoltage AGM as it will kill them very quickly so it is important to have battery temp sensor about half way down what will be your hottest cell and your charge voltage and max current set correctly, You do not equalise ...

Re: need dual battery cables if I only have 1 string?

The inverter is 8000/48 = 166 amps continuous and a reasonably easily obtainable surge of 12000/48= 250amps which the fuse sh...
