In reviewing my logs I'm noticing the voltage and amperage doesn't properly add up. The Quattro's voltage/amperage is different than my shunt, my mppt, and my batteries BMS (SOK).
At a minimum the battery BMS and and shunt should be identical or very very close to account for 3ft of cable losses.
The quattro added to the mppt should equal the shunt or very very close to account for losses.
Even the log times are off, sometimes its 10 seconds others its a minute.
Time | V at inverter | A at inverter | V at shunt | A at shunt | V at BMS | A at BMS | V at solar | A at solar |
