Technical FAQs 4

How many volts can a 100m inverter run?

Somebody has a 100m run from house to panels, and decide to use the legal minimum wire size (e.g. 1.5mm2 for 10A) with no bump for voltage drop/distance. As a result, it suffers a 25V drop @ 10A. The inverter must make 256V for it to be 231V when it reaches the meter. (panel voltage must be higher than grid voltage or current won't flow.)

How to calibrate the AC voltage displayed on the inverter?

nd the ACvoltage displayed on the inverter. If the tolerance is more than 3V, please calibrate the detected A :Fig.2 AC voltage shown on inverter displayConne the inverter to PC via USB to RS232 cable.Open the software, ShineCHK c to calibrate AC voltage as below picture.Disconnect the AC breaker, then type the whole number

Why does a solar inverter drop 25V at 10a?

As a result, it suffers a 25V drop @ 10A. The inverter must make 256V for it to be 231V when it reaches the meter. (panel voltage must be higher than grid voltage or current won't flow.) The more power being generated by solar locally, the higher it must push the voltage to push that power onto the grid.

Why does my inverter show AC V outrange?

verter’s voltage limits is incorrect, etc.If there are several inverters in parallel, and one or more inverters show “AC V Outrange” after the inverters feed electricity to grid for a while, this might be caused by high impedance between the inverter and feed-in point, please record the AC cables wiring condition and record
