Hi Guys,
I haven't been on here for a while and was just wondering how most people are interpreting the DTI guide 1% voltage drop recommendation nowadays?
Is the only way to be 100% sure that inverters will not ever drop out to design to 1%?
And when meeting 1% requires enormous cable sizes (eg farm outbuildings with 100m AC run) are people just installing a smaller cable with a slightly higher VD and accepting a risk of some downtime?
To share my experience, I have installed loads of systems where the VD has been a bit above 1%, and 99% of those operate just fine. However, there have been problems with inverter cutouts on a couple.
Thanks in advance for any replies.
