Having brought a bank of sulphated batteries back from the dead (now a SG of 1275+ across all 24 cells
) and having looked carefully at standing loads in the system together with the output of the feeble PV panels we have, I can see that I need to run my 240V generator once a week for an hour. The installation is entirely "off grid" and may go a couple of weeks without a visit.
I had been advised by the designers and installers of the system that they had programmed the system to run every Friday for an hour - the "exercise cycle". Of course it doesn't - they hadn't read the manual ... "The generator will run once a month at this chosen time during the first occurrence of the chosen day."
Noise and diesel considerations mean I don't have an entirely free hand as to when to run the generator.
The PV panels seem to leave quite a surface voltage on the plates, and so the voltage as sensed by the mate doesn't drop appreciably until the night or late evening which is a "quiet time", so I'm not sure how or if the AGS Voltage Start can be used.
Sometimes the premises are used as a quiet retreat by non technical users over the weekend and it would be inappropriate to use the "Weekend Exercise" facility, and, as I understand it, that is both
Saturday and Sunday, so doubles the amount of diesel used.
Is there a way I can get the generator to run once a week for an hour, dependably, apart from visiting the site and doing it manually?
