Off Grid solar inaccurate readings at higher watt levels

Configuration
1

Hello, with INA3221 at lower watt levels coming from the solar panel, HA shows correct values.
With higher watt levels from the solar panel, the HA watt values getting more inaccurate.
Example solar at 99W, HA shows 38W?

You have told us nothing about how you have integrated this with home assistant but it sounds like you are exceeding the device specifications.

Most INA3221 modules are rated for a maximum of 2A @ 26V, = 52W max. Some are rated for less than that.

I integrated it with a ESP8266 D1 Mini.

My INA3221 has 3.2A.
