My name is Samuel I am Brazilian from Santa Catarina


My project is complete, it takes a 7s recycled lithium bank with 144 amps initially.

Swipower 3000 Watt Inverter, MPPT Controller SUN21 - CCS-M4024.

Nice, and with plenty of space for battery expansion.
You've designed this for max 25kWh? I hope the case is really really well secured to the wall. It'll get quite heavy.

It looks like the battery case is well sealed, sitting outside in the sun. Have you measured how warm it gets inside the battery case? Heat is one of the killers of LiIon cells. You might want to put up some sort of shade. Or even add a thermostat controlled ventilation, if it should get hot inside.

Good morning, 

this is the working prototype of my inverter output monitoring application, and the utility input to my system, below is a graph in watts of near real time consumption (1 minute delay).
System developed with Raspberry, androi-studio integrating with google cloud (firestore and firebase), and Sonoff pow R2 with active mqtt (tasmota firmware).

A little more will be showing the tensions of each of the S
