Yes agree and i think your strategy to leverage the EoL state is great. In BR i have Lead-acid and in Portugal I installed Lithium. I can say there's no comparison between them when it comes to performance. So, it does pays you back every penny. The problem i have in Brazil is that is crazy expensive to buy them - so financially it doesn't worth it.
I can confirm with Lithium it never happened with me. What i have in my setup is more or less the summary below, happy to share more details:
2x (
DIY Lithium
16s280ah prismatic
Daly BMS 200A
Daly 5A active balancer
Esphome -> Serial to DalyBMS -> Wireless to Home Assistant
DalyBMS -> Growatt through RS485 (Plyon protocol)
ESPhome controlling battery heater
)
As I have two battery banks, i am only connecting one battery bank to Growatt. And i am managing the load/charge between both banks by HomeAssistant/nodered automation.
All good, looks simple but there are some key components. The system can live without homeassistant, all major functions are present without automation, but some safety routines/balancing etc does need automation from HA.
Happy to share any other details you (or anyone) might be interested.
BTW- i choose to start with Daly products, There are tons of people complaining about them and recommending other BMSs. I have nothing to complain so far, fortunately.
