I would appreciate some help with the settings for ESS on my system, I have a:
Multiplus II 12/3000/120
10x 12 volt 100W solar panels
MPTT 150/85 - TR - VE.Can
Smart shunt
Venus running on a Raspberry Pi
Li-Time 400 AH battery
a home wired to North America standards (110v)
I have on order a:
STC-013 sensor which I plan to connect into my Multiplus
How I would like to set up ESS is as follows:
- keep the battery fully charged at all times unless there is a power failure (the ESS setting for this seems clear)
- Have, as a first priority, the PV power coming in used to charge the battery
- Have any excess PV power redeployed within my home, to a maximum of 10 Amps
- NOT have any excess PV power from my system feed into the grid (if my PV power coming in exceeds the amount of power needed to power my home, then that power should be forfeited/go unused but it should NOT feed the grid)
- Have grid power coming in charge (top up) the battery only when I set a setting to have this happen (otherwise it would normally wait for the next day when the PV power can do this)
- Have the inverter normally off, but in the case of a grid power failure have it (the inverter) turn on
(I could do this manually if needed)
- I don't need multiple phases
In order to know how to set this up, I've watch the ESS setup video and read the ESS instructions at https://www.victronenergy.com/media/pg/Energy_Storage_System/en/configuration.html#UUID-d5ba0921-8b24-03ea-5400-f17704a4071c
plus searched for examples of similar setups and watched some related Youtube videos, but I feel I need more of an explanation.
If anyone has documented such a setup up and would be willing to share that would be great.
Thanks in advance.
