PV Battery Charging Limited at 4kW
Hi, I've got an 8kW inverter with a 14.3kWh battery. I've got the battery charge limit set to 185A DC with 8.2kWp of solar installed. During peak hours of the day when I know we could be producing more and charging faster, it still limits the charge to about 4kW. You can see the solar pick up when there is a load.

Check what the LiBMS screen says. The BMS can limit the charge rate based. Mine reduced the charge rate from about 90% SoC. Also check that your firmware is up to date. I had a strange problem and it was resolved with a firmware update. In May 2022 I upgraded to SW Ver.：M 6.0.1.4 / S -- / C E.4.2.4
Working well since then. https://www.sunsynk.org/forum/techical-support/help-sunsynk-8k-prioritising-battery-over-solar
