Hi all,
I am in desperate need of some help. I am living "off grid" due to unforseen circumstances for the past 4 months now. I purchased a 3.6kw 24V Inverter, 8 X 200ah deep cycle batteries & 5Kw Diesel generator (no name chinese make). Basically I run the genny during the day to charge up batts, warm the geyser & do laundry. 2 days ago whist charging, I heard the inverter click over to inverter mode. I went outside & saw the volt meter on the generator was 0. I shut it down and started checking wiring, fuses etc... to no avail. I started it up again & noticed the Voltage gradually building up to 220 then falling back down to 0 continuously (motor running stable). I left it for a few hours & started it again - No voltage. I searched on-line & came to the conclusion it must be the avr. I took out the avr (it looked fine to me), went out & bought another one. Installed it - No voltage! I then decided to flash the genny by putting 12V dc on the brushes whilst motor was running, then reconnect avr - It came to life.... sort of. The voltage gradually rose to 220v, but after about 10 minutes or so, the voltage started jumping around (never more than 220V though), then back down to 0 & hasn't worked since. I managed to get some voltage out of it again by applying 12V directly to the brushes while the motor is running. The voltage is stable as long as I keep the 12v supply on the brushes, but doesn't work at all with the avr connected. Can anyone possible help point me in the right direction. All the tool hire shops are closed until after new year. My family & I are starting to take strain now. I have read a few threads on this forum & noticed "oztules" seems to be a genny repair guru. But any help from anyone will be greatly appreciated. Thanks in advance.... & sorry for such a long first post.
