Yes, I wouldn't worry too much about those startup peaks. Question: Is this seemingly normal for a 150W rated fridge to start with such a high surge? I know about motor surges but this is about 6x its rating! However, the 0.5HP sump pump (circulates fish pond water) has a modest spike a fraction of the fridge despite a higher continous running draw. This has been consistent, each time this fridge starts for milliseconds it spikes this high. The main frige, A Defy Refrigerator with a rating of A+ and a stated annual consumption of 478kWh per annum and name-plate consumption of 150W (see attached pics) seems to have a very high starting watt draw which spiked the load by 1kWh. I also monitored the PV early morning generation (thanks to ICC) and one load aspect caught my attention.

Question: Is there any benefit in puting the panels in 3x series? I note reading about that most seem to have them in this style. What seems odd though is the current which was all over the place. Infact as the day progresses the PV voltage flatlines around 68V. Temperature is comfortable despite the onset of the dry season with day time temp peaking around 30 degrees. From the attached ICC screen capture the voltage curve seems to be acceptable especially that I monitored early morning. The arrays are in strings which have 2x series (VOC close to upto 76 range recommended in manual and Vmp about 61still within range). E&OE.I've two arrays connected to the inverter facing east and north (just discovered and innovated a wall mount for the north wall, can only accomodate 6 panels).
