I have the Freedom 20 (100 amp Charger with 2,000 watt inverter) and the Link 2000 battery monitor. I replaced my batteries this past March, swapping out 10 Trojan T-105's in the House bank with the identical batteries.
I am concerned that the link monitor is "loosing its way" with the number of amp hours consumed. When I am on AC, and float charge, the monitor indicates a slow battery usage of about 10 amp-hours per day. The system is on "float" charge. Battery voltages indicate to me that the system is charging properly and when I am off-grid, voltages seem consistent with the amps consumed. However, when I go back to charge, it seems the system returns to "accept" and float charge states prematurely, with a residual "negative" amp-hour reading. Because of these concerns I have been careful not to discharge the batteries by more than 250 amp hours (1125 total capacity) and I have been diligent with using the generator twice per day for an hour or two, even though its not the most efficient use of charging with the lower charge acceptance rate.
As the charging system and battery monitors are circa 1998, I'm thinking it is now time to upgrade the setup before the system fails. I met a long time KK 42 owner at the PNW "Krogin" this past week and he is very pleased with his Magnum 2812 Inverter/Charger and the Magnum Energy ERC50 control panel. Also, a brand new KK 44 was commissioned with a Magnum charger (not sure which one) and also the Magnum Energy ERC50 control panel. The control panel displays SOC as well as the usual voltages amp-hours etc.
When I go through this change, I will also reconfigure the cabling to the battery banks to ensure uniform charging across the units. I believe there are a couple of tweaks that can be done here based on recommendations from "Clectric" as well as a marine electrician who was quite helpful.
Thoughts from the group?
