There is a group of battery junkies or solar enthusiasts that have been posting in an effort to get the most out of their batteries while boondocking and improving general longevity. One common device that is mentioned frequently is the Trimetric TM-2025 RV battery monitor. This is a product from a small California company that specializes in monitoring products for solar, wind and water power.
Bogart Engineering has just announced a new version of their TM-2025, they will soon be shipping the TM-2030. Beside simplifying the setup process the new monitor will talk to a new product they will release this month, the SC-2030 charge controller
. This is the product I am most excited about.
I have been very frustrated in finding systems: both built into the trailer and solar options that will charge at the battery manufacturers recommended level. Here are some threads to bring you up to speed.
Portable Solar and Monitor Location
Replacing stock WFCO converters
Interstate 6 Volt Charging
The information is still brief on Bogart's new solar controller, but here is a quote from their website:
One distinguishing feature is the ability to program the amount of excess amp-hour overcharge, as recommended by US Battery, Trojan, and other major battery manufacturers. A four-stage charging algorithm optimizes both battery life and charge-discharge cycle depth.
At this time I have only been able to find two solar controllers that come close to the recommended charge levels recommended by Interstate Batteries. The Morningstar TriStar 45 and the Xantrec C35.
As an aside, wouldn't you know I just ordered a TM-2025 and had it delivered to Escape for installation.
