Installation wiring concern

Hi All,
Just had my system installed today - 9.5 battery but Gen 1 inverter (no Gen 2 available apparently) - and the cable linking them does not fit the inverter.
The installer spoke to GivEnergy directly & was told he'd have to get another cable (limited supply), with obvious delay in commissioning. He then spoke to EOn (who he was contracted to), who apparently then spoke to GivEnergy, and was ultimately told to cut the end of the cable at the inverter side & wire it directly into the inverter.
I have no idea if this is OK - the system is running & completing battery calibration as I type - as the installer only informed me of this as he was leaving at 6pm......
The cable had orange sockets, if that makes any difference.

I was also expecting the EPS to be wired up today - whole house, manual switchover - but the installer had no record of that. He said I'd have to chase it up through EOn (I've been waiting over a week already, as I'd raised it with them previously when the surveyor failed to follow up on it), so getting a bit cheesed off now!

It’s up to GE I guess but in all honesty I’m not sure why this isn’t just the normal procedure anyway. Would save so much faffing about with two different cables that nobody can get hold of - one of which is just the same cable without the orange plug on both ends and instead fitted with some ring crimps (presumably exactly what your E.on installer recreated I guess)

But that’s just me and I’m not Givenergy so provided they are truly happy and it wasn’t just made up to get it going and out the door you should be fine.

hoggy thanks hoggy. Makes me feel a bit better overall.
As long as the house doesn't burn down due to a battery fire overnight, I'll update tomorrow!

Cilonen wire it directly into the inverter

Does the gen2 installation not have a battery isolator for the cable to be terminated into? Feels like a missed opportunity if not. Mind you, given the apparent reliability of the battery isolators, maybe that's a reason not to.

Sounds like neither the surveyor nor EOn want to do this and I can see why. Obviously, you understand that the normal house load cannot be fed from EPS (even a 3.6kW gen2) so you will not be switching on any heavy loads such as kettle or oven or electric heaters, while you have a power cut; just lighting and small appliances like router and TV. But if you ever sold the property, the new owners might not remember the dire warning of inverter damage and they may try to run the house normally.

Tim Yeah, it's just wife working from home (& me some days) & being able to just "carry on". That's also why I opted for the manual switchover, to ensure any high loads were shut off first.
Have a gas hob so boiling water wouldn't be an issue.... 😄
