I am working on a project where I want to provide a portable power solution.
To achieve this I am considering using the Victron MultiPlus and a 12V AGM battery.
In order to make the system user friendly I would like to display the condition of the battery.
This needs to be simple for the guys using it.
To achieve this the best way I had imagined was a display with 4 LEDs which indicate would indicate charge level* i.e.:
LED1 - 90% - Over 75%
LED2 - 70%
LED3 - 40%
LED4 - 25% Recharge at this point
% levels are approximate and could go from 0 - 100% if easier.
A screen which could display this information would be suitable.
When charging this same display could be used to indicate charge progress.
LED1 - Charged
LED2 - Float charging
LED3 - Absorbtion
LED4 - Bulk
Appreciate that % of battery charge is hard to precisely determine but I am basically after an indicator for how much useful charge remains for usage or whether it needs charging.
Am wondering if there is someone who is familiar with Victron products.
Is there a Victron product that can achieve this functionality or something similar?
It is important that the interface is simple to use.
My alternative option is to put a simple battery meter (I believe this works on preset voltage levels to approximate capacity). However am unsure what this shows whilst charging, imagine it would show over 100%
Hope someone has a suggestion.
Thanks in advance for your help.
