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 nominal battery bank. I'm adding array (6 x 60-cell generic), replacing batteries (FLA with VRLA), and updating disconnects and overcurrent protection. Can anyone suggest a user-friendly system monitor that will work with this system voltage, something akin to a TriMetric 2020 or 2030? I can't think of one that will work with a system voltage this high. Mostly I'd like the percentage function for a nontechnical homeowner.

Thank you, Allan
