February 6, 20233 yr Hi all I recently got a SunSynk 8KW based system with 12x JA solar panels and 2x Hubble AM-5 5.5Kwh batteries. Highly pleased with it. However, the Sunsynk WILL NOT consume any more than about 1.2Kw from the town council over the AC link - anything higher and it disconnects itself and draws off the panels / batteries. The installer showed me that the problem is that when anything more than about 1.2 to 1.4KW is drawn from the town council, the voltage drops on my municipal connection to 170 volts, and sometimes as low as 145 volts, measured at the input side of the DB where their cable enters. He disconnected the inverter, and even with it not touching anything, this severe voltage drop is apparent as soon as you, for example, boil a kettle and start the swimming pool pump (about 2200 watt load) - the volts even went to 140v at one point on their cable before the DB, with the inverter physically disconnected "downstream". If this happens while the inverter is connected, it disconnects itself from the AC supply as the voltage goes way too low. How can I try to explain this to my council - like almost all councils ours is bankrupt and infrastructure is falling apart all over. It is virtually impossible to get any kind of response out of them, let alone say "there is a voltage drop on my connection if I draw more than 1.2KW". It is next to impossible to get a municipal electrician on site. Any pointers or ideas where or how I can approach this? Can the fault be on my side somehow? Thank you
