Off Grid Monitoring Solution

f1ct10n · Aug 24, 2022

Hello,

I'm currently running a Growatt SPF 5000 ES inverter with 8 batteries.
Monitoring the system using the ShinePhone app. (Growatt WiFi dongl installed)
I'm seeing a lot of inconsistencies on this app, battery charge levels jump around a lot; screenshots attached.
Also there are only 4 battery levels available (0%-25%, 25%-50%, 50%-75%, 75%-100%).

Is anyone using this app seeing behavior like this?
I know that there are no batteries that can charge/discharge this quickly, so I know the issue is not the batteries.
This leaves either the inverter or the app as the culprit, and I'm having a hard time identifying what is causing this weird behavior.

I've also seen in other threads people recommending the SolarAssistant app, I'm open to using other monitoring solutions if they are better.

I have the same inverter and Solar Assistant.
It's great. Wish I would have switched sooner.

sure would be great to be able to get a Raspberry Pi for a reasonable price.

without BMS connectivity to the Growatt, SoC does not work with the Growatt dongle.

is anyone aware of a standalone monitoring solution that isn't based on the raspberry pi? I'm not paying $150+ for something that should cost $30.

I have a Victron smart shunt reporting SOC to Solar Assistant. I chose the smart shunt because it is compatible with Solar Assistant.

SolarAssistant is the best. Growatt is dependent on slow Growatt.com server update timings. Solarassistant has much better charts and reports.
It updates every 10 seconds or less without depending on an exterior internet server connection.

If I can do it, you can do it.
