I'd like to get your thoughts on my planned installation, i have a couple of choises and would like your input.
I have a quite reliable grid (as of now, might be different in the future), but i have equipment that require uninterruptable power, and i plan on installing solar panels which i would like to use even when the grid dies.
So my goal is to be able to primarily use solarpower myself, secondary is to charge batteries if they need to and tiertiary sell excess power to the grid.
When the grid fails, i would like to continue to use solarpanels, when batteries reach a certain SoC i will start the generator which will take over until the grid comes back.
The setup would look something like this:
It will consist of three Quattro 5kVA in ESS mode (3 phase), one Venus GX, Lynx busbars and four 12V 190Ah in serie.
I will mount the panels on the ground for best angle and direction (roof is not well suited) and becouse of that i will have a long cablerun from the panels to my house.
That gives me two choises.
One: Run high voltage DC from panels to house.
Two: Convert to AC at the panels and run more expensive cable to my house.
What's my options for connecting the panels to my quattros and batterybank? I don't think either the Quattro nor any of Victrons MPPTs can take that high voltage?
It feels better to put all active equipment at the same locked place (my house) rather then having a DC to AC converter at the panels.
What's your recommendations?
Kind Regards
M
