16) PV ISO
PV ISO value is used to confirm earth issue on PV side. Once it exceeds 50KΩ , the inverter will alarm. Normal value is 65532
17) R_DCI, S_DCI, T_DCI
The meaning of DCI is that in one cycle, positive wave value of AC current +negative wave value of AC current =0 for normal situation, once DCI value is not 0, it means the inbalance between positive wave and negative wave is occuring. It may be caused by Grid or inverter by itself.
DCi explanation:
DCi goes 0 when the sum of sampling currernts is zero,
otherwise there will be a DCi bias value showing in history data.
The standard DCi value is less than 0.5% of the maxinum current in AC output at fulll load.
It will affect the AC output quality if an inverter produces high DCi .
17) PID_BUS
PID circuit is like BOOST circuit, which is used to promote the voltage between positve and earth, this BUS voltage is formed by PID circuit.
18) GFCI
Ground fault circuit interrupter
GFCI is used to judge if AC side has earth issue, the principle is like RCD, once 3 phase inbalance, it will detect the current. In usual, it should be less than 30mA.
level1: leakage current>30mA-off grid reaction<200ms
level2: leakage current>60mA-off grid reaction<60ms
level3: leakage current>150mA-off grid reaction<20ms
