I am using a Balcony Power Plant based on 4 x 500 W Panels, 4 x Growatt NOAH 2000 and Growatt NEO 800M-X. All connected to Growatt Cloud and bound to HA with MQTT and Noah-MQTT.
What i wonder about is how the system is behaving.
For example the SOC1-4 Values are sometimes “switching” like the value for SOC1 is taken over to SOC3 and vice versa. Or there’s a jump from 64% SOC (overall) to 100% in 10 minutes (same for SOC1-4) that is impossible.
The system is loosing 8 % SOC in 14 hours means about 650 W in “standby” / battery first mode over the night with 0W output?
How can you manage the generated power if there’s no stable / accurate info about the remaining energy?
- Is this problem limited to Growatt devices or is there similar experiences for other vendors?
- Is this a problem in the Growatt Cloud / Devices or with the used Addins in HA?
At the moment i can not really trust the values making it very complicated to manage the produced energy efficient.
Any input from the community to this topic?
