I believe the best way to utilize potential excess energy in a PV installation is to use all available data and set up rules for when (and how much) excess energy is available.
Last years story about AC-THOR involves a separate HW (non Victron) and use the CCGX as data source. In a couple of other threads on this community the solution is also to use additional HW, or the more simple solution only using one data source, i.e SOC = 100% flip a switch.
I do not understand why we need additional HW, and the "one data source, flip a switch" is way to inefficient i.e not being able to harvest energy when the MPPT throttle down in the absorption phase.
I have experimented with utilising the VRM alarm rules, and building the logic into my Gmail email filtering functionality. This is possible to accomplish by controlling the load basically by sending emails to my "Smart Cabin" using the simple and inexpensive functionality that comes with services like IFFT.
So.... for installations that have all the nice and advanced HW from Victron, MPPT, BMV, Multiplus, GX's , and are online to VRM with local inexpensive SmartCabin functionallity like Telldus. ..........
Why... can't we just get the logic built into the VRM portal very much like the alarm rules?
MPPT in Bulk mode - everything goes to the battery - no excess energy available
MPPT in absorption - apply load phase 1 (jut send me an email if you do not want to link directly to IFFT
MPPT still in absorption and PC power is increasing and battery voltage not dropping? apply load 2,
etc etc etc
Dear Victron experts - this ment as inspiration to make even greater functionality on the VRM portal
