Hi guys I hope somebody can shed some light on this problem.
We have installed (as a subby) 10 sharp 235s on a SB 2500 initially got an error which was a replacement inverter job.
new inverter same problem.
Changed inverter to 2000HF a nice bit of kit and really what i would have specced if it were my job.
this inverter is slightly easier to communicated with via bluetooth and sunny explorer.
what occurs is as the inverter starts to feed the grid the voltage rises to 264V and trips the inverter as it should.
The grid voltage at origin is 248V a bit high but nothing out of the ordinary in rural Cornwall.
I changed the upper voltage threshhold settings for a bit of a test and the inverter was peaking at 275V while generating 1kW what is going on?
Things I have checked: cable size 4mm from inverter to garage board length 1.2 m (SMA in Germany said this is perfect)
All AC testing giving great readings insulation resistance etc all as they should be no anomalies checked all connections all good!!
I have visited this job 5 times trying to sort this, i and the customer are going mental
Thanks :cry_smile:
