Comparing the Blue Sea 7611 to the Surepower 1315
I need to buy a battery separator for my build and I've been comparing the Blue Sea 7611 with the Surepower 1315.
These appear to be very close in functionality (bi-directional charging), with the following differences:
Continuous amp capacity for the 7611 is 120A and the 1315 is 100A.
The 7611 draws 150ma vs 750ma for the 1315 when energized. The 7611 would seem to help the issue of burning up close to an amp when solar charging, a common complaint of the 1315.
The 1315 has a 400A intermittent current rating (30 seconds on/6 minutes off duty cycle); the 7611 is 210A for 5 minutes.....hard to compare here apples and oranges.....may not be that different, although the 7611 states that it's not designed for starting current.
For some reason, the 7611 is limited to group 27 battery banks....??? If the stock Ford alternator puts out 115A, why should the bank size matter?
Is there anything else I'm missing here?
My house batts are 2X 200AH AGM's, and I'm tempted to try the 7611, although I'll be way over a group 27 size aux bank.
I don't really need the bells/whistles of the 500A Blue Sea unit, and I will be installing a solar panel/controller so I do want bi-directional charging capability. The van will mostly be used on weekends so the idea of solar charging the starting battery while it sits all week is appealing.
