Hi
Everyone has a bit different wants / needs
I have both the Trimetric 2025rv and the MS TS-RM2 remote meter w/ my MS Tristar MPPT 60 system. The two displays are complementary with different data being displayed.
I look at my system as a power source NOT simply a battery charger. The TS-RM2 shows what the power source (550watt PV array)is doing as in supplying power to the Inverter and other large 12 volt loads, power that never reaches the battery bank. NO way for the Trimetric to see what's happening when no current is coming from or going to the battery bank.
IMHO both displays are important if you want to see what's happening
PS - I have seen over 40amps on the TS-RM2 with a negative 5 amps on the Trimeteric. Clearly shows the PV array was supplying the lions share of the power to the inverter
