Home energy storage batteries support dual solar and grid charging with standardized charging and discharging rules. Use matched solar panels and grid voltage for charging, and avoid random wiring and overcharge to prevent damage to BMS and cells. Do not deeply discharge the battery or place it in a low-power state for a long time, which will cause capacity attenuation and increased internal resistance. Long-term full-power static placement is also not recommended; circulate charging and discharging according to peak-valley electricity prices. Stop using and power off immediately if abnormal heat, noise or charging interruption occurs to ensure power safety.
