[RE-wrenches] Off-grid system monitoring

[Maverick Brown [Maverick Solar]]

A good replacement is the Bogart TM-2025-A. It is a refreshed version of the
TM-2020. It can handle 12-48V and can display Watts.
 
You can also use the Bogart PentaMetric. It will cost more, since you will
need a "sending" unit, a display and it can even add a serial interface to
talk to a PC. Speaking of "PCs", you can also add a greenMonitor Lite with
the PentaMetric option. It works pretty well and can send email and has a
small web interface of what is going on. Of course, all that will add up in
cost...
 
Another gizmo that I like to use (but does not show amps/AH, so sorry for
bring it up) is the MidNite Battery Condition Monitor. It is a simple device
that keeps track of when the last time the batteries made it to Absorb. It
is a simple & cheap "idiot light" style meter.
 
Good luck!

Wrenches:

An off grid client has a system monitor that has not been very a
satisfactory.  I belive it is a Trace Meter 500.  It is not calibrateable
and the results are not reliable.  Is there a newer monitor that will show
battery voltage and charging and discharging amps and amp/hours that any of
you could recommend?

Thanks in advance!
