Re: Easy Solar Panel Mount

If is a basic shunting controller that turns off at 14.2V and comes back on again at 13V... It will prevent over-charging but that's about it...

Re: Dueling Charging Systems; Solar, Engine, Battery Charger

If you assume your bank to be 380Ah not 400Ah then you should test it at 19A not 20A to conduct a 20 hour test. Course if you are trying to identify where the battery sits for state of health, then...

Re: Do I Need A Solar Charge Controller?

Just that at night, when not charging, you're leaving both banks in parallel during potential discharging. Best to use an ACR (combining relay) or Echo or Duo charger between house & start/reserve...

Re: The deal with AGM batteries

*Bring battery to 77-80F and hold this temp steady - I use a temp controlled water bath like many battery manufacturer labs do (stole the idea from one lab I was visiting):wink.

Re: The deal with AGM batteries

#1 Yes I believe some boaters lie, seen this first hand, though I don't believe it is always intentional.

Re: Dueling Charging Systems; Solar, Engine, Battery Charger

There is no Peukert's compensation for a 20 hour test. The battery should deliver 100% of rated Ah capacity at the 20 hour discharge rate, at 77-80F without a Peukert correction. Deep cycle flooded...

Re: Battery Woes

If one opts for AGM I would really urge them to buy a premium AGM battery such as Nortstar TPPL AGM, Lifeline AGM, Odyssey TPPL AGM or the Firefly Carbon Foam AGM.

The Deka / East Penn product is...

Re: Battery Woes

I am going to assume these are Interstate SRM group 24 batteries. These really are not a "deep cycling" battery despite how they are marketed. Two years under deep cycle use with no method of knowing...

The top was closer to a hard top dodger with aluminum framed windows forward and EZ2CY/Stamoid curtains aft. It was not a part of the boat, as in being glassed on during layup like many production...

Re: Dueling Charging Systems; Solar, Engine, Battery Charger

Re: solar recommendations - question for MAINESAIL

Re: Dueling Charging Systems; Solar, Engine, Battery Charger

If this load is below the 20 hour rate please don't do this.... I will let you think about why and it should become quite obvious.. I can answer more later but have to run out the door..

Re: Dueling Charging Systems; Solar, Engine, Battery Charger

You don't accumulate -Ah's on the Xantrex Ah screen by shrinking capacity you accumulate this by "drift", lack of manual resets when known full, or chronic under charging. What has been removed needs...

Re: Dueling Charging Systems; Solar, Engine, Battery Charger

It describes how to conduct a 20 hour capacity test, which is the only test that can accurately be used to determine Ah capacity for an Ah counter.

Whether or not this is "realistic" or if folks...

Re: Dueling Charging Systems; Solar, Engine, Battery Charger

Unfortunately most Ah counters, such as the Link or Victron etc., are so badly programmed even they are not accurate when relating to SOC. They also drift and get out of sync especially when solar...
