q
24v regulator is a Balmar 3-stage external unit (model MC-624, with a back-up
spare on board) and charges based on the selected profile. Standard Flooded Lead
Acid profile is BULK at 28.8v, ABS at 28.4v and FLOAT at 28.4v. Gel = 28.2,
27.8, 27.4. AGM = 28.76, 28.36, 26.76.
q
As of 2021 11 27 battery type is appropriately configured as “P04” which is
AGM battery type.
q
12v charger BULK charges until it hits 14.25v, ABS charges for 4 hrs or until
current is less than 1A for 15mins, whichever is earlier, then FLOAT charges at
13.25v. Jumper setting provides optional FLOAT voltage of 13.8v.
q
24v charger BULK charges until it hits 28.8v, holds for 4 hrs for ABS, then
FLOATS at 26.8v
Inverting
The 230v unit uses the 24v house bank and can provide continuous 50 Hz AC current of
18a, although I can’t imagine what that would do to the batteries.
The 110v unit uses the 24v house bank and can provide continuous 60 Hz AC current of
17a.
The inverters provide true sine wave output so they can efficiently run every device,
including ones with more sensitive electronics.
CSCP Set Up & Resetting
Press Set Up button for 5 seconds (the green LED will flash when Set Up mode is active).
Then briefly press the button for the function to be set up (blue lettering). The present
value will be displayed. After 3 seconds of pressing the function button, the display will
begin to scroll through the range of values that can be selected. Release the button when
the desired value is displayed.
The
Power Share
feature sets the AC current limit for battery charging to ovoid over-
loading available AC sources. To enter Power Share set up, ensure that the green LED
on the charge button is illuminated before entering set up mode. The selections are 5, 10,
15 and 20. The higher the number, the greater the amps available for charging. 10
appears to be a good setting for 30amp shore power service (20 will definitely overload
30amp shore service). The genset can handle 20.
The full-specification charging rate for the MV charger is 70 amps, which is what I see
on the CSCP monitor.
If the amp-hours monitor gets out of synch and/or the low battery warning appears even
though the batteries are charged, you can manually reset the amp-hour counter. First
completely charge the batteries (to the point that they do not accept any more than a
trickle charge at most), then select the desired battery bank, press Set Up for 5 seconds
and press Reset A Hrs for 3 seconds.
