[RE-wrenches] System Monitor for HV Off Grid System?

[Sindelar Solar]

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
