r/Deye

After working with different solar inverter brands over the years — including Huawei, Solax, Must, Growatt, and Deye — I’ve noticed that every brand has its strengths depending on the project and installation conditions.

But personally, one of the brands that gave me the best balance between performance, flexibility, stability, and price is Deye.

What I like most is how practical and flexible it is for technicians in the field. Whether it’s On-Grid, Off-Grid, or Hybrid systems, the configuration is usually straightforward, and the system performs well even under difficult conditions like high temperatures or unstable electrical networks.

Another good point is the compatibility with different lithium batteries and the ease of monitoring and troubleshooting compared to some other brands.

Of course, this is based on my own field experience, and every installer may have a different opinion depending on the type of projects they work on.

I’m curious to know:
Which inverter brand gives you the best balance in your experience?
And has anyone tested any new inverter brands recently that are worth discovering?

I’m still having issues understanding how to use the Deye firmware — it seems quite confusing.

I think I have a basic idea of what I want to achieve, but I’m not sure whether the issue is with my setup or the software itself.

My goal is to:

Charge the battery primarily from solar each day.
Top up the battery from the grid when tariffs are low.
From 5:30pm, discharge/sell energy down to around 25% battery capacity until 7:30pm, when the peak feed-in tariff applies.

The problem starts when the battery reaches 25% before 7:30pm. Instead of continuing to power the house from the battery, the system immediately starts drawing power from the grid.

The reason I want the battery to stop at 25% is so there’s still enough stored energy to run the house overnight and into the next day before repeating the cycle again.

What’s also frustrating is having to make changes online and then wait for the data and settings to update. There really should be a basic local web interface on the inverter itself, or at least a much better app experience.

I’m considering trying Home Assistant to see if it provides better control over the inverter. However, to me, that suggests the product itself is lacking. It’s disappointing that these limitations only become obvious after the system has already been installed.
