I would like to get your help with specifying a system
Ideally we are looking to get a 0 grid import of power situation during the non-peak rates.
Currently we are using 3500kwh a month in electricity and 1600kwh in gas. The longer term plan is to use Sunamps and/or ASHP to replace the boiler (that mainly only does hotwater).
We currently have a 3 phase electric system.
We are looking to create a “powerwall system” which decouples from the grid rather than pulling from the grid like Givenergy power packs do.
I’ve been looking into it and it seems a Victron multiplus II seems like the unit to use to create this system with Pylon batteries.
We will look to install a solar array as well (circa 50-60 panels) all south facing. So we need systems that can communicate with each other and take the load.
I’ve estimated that we will need atleast 30kwh (but most likely 50kwh) battery power to last the day using off-peak tariff but we need to ensure that we can charge up all batteries within a 5-6 hour window.
We have access to plenty of electricians that have installed PV systems but do not do the software side of the installation. Ideally we would like to us our in house programmers to setup the system. Whilst we understand that we wouldn’t have MCS certified setup that is not an issue for us.
Previously we have bad experience with solar companies going bust or having limited support hence why we don’t want to be reliant on them going forward.
Can someone recommend what would be good or a setup able to meet these needs and future needs.
