I am having a problem at an Off Grid job in Lancashire, which comprises of an array of PV panels, three batteries an inverter, and an backup generator which does not fire up automatically but currently has to be switched on manually.
I did not realize this park home was totally off grid when I took out their WB non condenser and hung the Intergas 24/18 on the wall.
The PV Panels, batteries, Inverter and generator are housed about 75 yards away from a park home.
There are at least two earth rods, one at the stables where the Inverter, batteries and generator are and one other earth rod is 75 yards away underneath the Park Home.
The boiler runs for a few hours then locks out on 4.
At one point when I was in front of the boiler the burner would light and drop out after one or two seconds then lock out on 4.
There were earth problems initially, L to N 230, L to E 120v and, N to E 110v
The electrician who supplied and fitted the Off Grid stuff sorted the L t0 E and N to E and
I am now getting 4.39 Ohms on my Socket & See Multifunction Digital No-Trip Loop Tester, its model PDL 310 and 38mb at the new LPG bottles change over valve/Reg and new flexible to the 22mm copper pipework.
In an effort to solve the problem I changed the pcb, gas valve and ign module, these part work perfectly on my own boiler
Last time I was at the job I got ionization readings of 2.1 & 5.2 when running in L and holding in the + button.
I removed the existing fused spur and replaced it with a single gang socket and a plug top which gave a constant ionization reading of 4 micro amps but the boiler still locked out later in the day.
According to the customer the boiler will not successfully relight immediately after locking out on 4 but needs half an hour before it will stay on.
The 20 year old non condensing boiler I removed did not use flame rectification to prove to the boiler pcb that there was a flamme present where as condensing boilers with pre mixed burners need a good earth.
Has anyone got Off Grid experience?
