250watts *2.
1A, 2.
The battery was able to hit 12.6 that full charge since buck converter was set to that.
what's even the essence of adding buck converter to panel before connecting to cc, can't your bms handle up to 14v?

First Build

Purpose: To power an entire house
Configuration: 3s70p (210 x 18650 batteries)
Voltage: 11.1V
Connection:
Solar panel → Buck converter → PWM solar charge controller → Battery with 3s BMS → 3000W pure sine wave inverter.
Performance: Current cut off at 10.5V when powering a fan or a 12W bulb at night.
Status: Failed to meet its intended purpose.

Second Build

Configuration: 4s56p (224 batteries)
Voltage: 14.8V, 13.8 when powered.
BMS Cutoff: 10.5V
Observation: PWM solar charge controllers are not suitable for lithium batteries as they drain the battery instead of charging it.

Next Step:

Tomorrow, I will test the following setup to evaluate its success:
Solar panel → Buck converter → Battery with BMS → Inverter.
I think your cells are bad.

OK sir.
Thanks.

But you are supposed to charge at 12.6v or below at say 6amp depending on the buck converter. Some manufacturers will state that a fan should be attached to care for heating.
I want it fast charging, the bms can handle the voltage.
