mastervolt soladin 600w grid tie fault

[seiko]

Hi first post, hope some one can help, I have 2, 12v 100w solar panels in series to make 24v system, panel specs are

Dimensions (H xW x D) in mm 1060 x 669x 35​

Cells permodule 36​

Weight in kg 10​

Power max.(Pmax) 100 W​

Voltage max.18.75 V​

Current max.(Imp) 5.36 A​

Open circuitvoltage 22.06 V​

Short circuitcurrent 6.02 A​

I have purchased a mastervolt 600 grid tie inverter, in good sunlight If I connect it up to the panels I get nothing no lights or response from the inverter,measured voltage on the solar and I am getting 43v open circuit but the inverter does not respond,​

I have another two 100w 12v panels on order to wire in series for 24v but even with the panelsI have I would have expected the inverter to do something, concerned now I have bought a dud unit of ebay, any advise please, thanks in advance​

The Soladin has an MPP voltage range of 40-125V, which is more than your two panels will produce when connected to the inverter. Adding another 2 panels in series to your existing 2 should sort you out.

As per above you need at least one more panel in series
