i have a fg wilson genset max power output 15 kw connected to an offgrid SMA solar power system 16 kw capacity, there is two 8 kw inverters connected together.
the generator is used to charge 24 lead carbon batteries on days with limited sun
the system has worked without problems for 4 years, a few months ago the generator went over voltage, set usually at 240 volts 50 htz ,
went to 320 volts
i checked all connections and replaced the genset voltage regulator, and the fault still occurs intermittently
any ideas where to look next
