Right, it lacks many features. Old school method: tape a piece of paper next to the meter showing AH removed = xx % full. I think any shunt up to 1000 amps can be used. It can be programmed for different styles. It also has two programmable relays to start a generator or notify the user to char

I would go for an Egauge system.I can work on 144-volt battery, and report the battery voltage, it can report easily the currents. Egauge has some new functions that make mimicking a Trimetric possible. problem is going to cost more than Trimetric. However, it has far greater monitoring capabil

I actually saw one of those once, they did a presentation. Seemed like a good idea, but they never had a good answer on charge controllers and other equipment.  The E meter can work at higher voltages.  I used them with 144 vdc battery banks before. Ray Walters On 10/20/17 3:48 PM, Sindelar

Wrenches, I have an upcoming remote residential off grid upgrade job that uses one of the rare Michigan Energy Works inverter/charger/controller packages, this one from 1997, which the homeowner wants to continue using. The package uses a 120 volt nominal array (10 x BP90 in series) and a 144V
