1. The batteries are named AAChampion, model C12V325. They are imported into New Zealand by AASolar a reputable solar dealer/installer who have been in business here many years. They are made in China by UPG. The batt spec sheet recommends 58.8 for Bulk, Absorb time of one hour for every 200ahr capacity used per cycle, and Float of 54.8
2. There is no setting for Bulk on this CC. The manual simply says "100% of available solar power is used"
3. Absorb (which this CC calls Boost), initially was set at 58.8 at suppliers recommendation when installed in mid-May, but when the OVD first started in early July the supplier recommended lowering that to 58.4, which is where it is at now. Absorb time is set for two hours.
4. Float is set as recommended at 54.8. I am a bit concerned, wondering if this is another sign of a faulty CC, that only twice have I seen the CC showing Float. It goes all day at Absorb despite a time limit of 2 hours. The supplier explained the cause being "Not enough sun to deliver required voltage for a continuous 2 hour period, so the CC will wait until it has accumulated 2 hours worth before switching to Float".
5. EQ is disabled
6. The CC has a built in monitor on which I can cycle through 7 interfaces to look at data. One of them shows daily Min and Max voltages. Usually Min shows something in the region of 50.5, and Max shows 61.5 or thereabouts, at which level the OVD happens.
