I am still new to 5kw Sunsynk, installed and running since Feb 2021 with a 7.4kw SolarMd battery and 4kw of Panels, (Started off with axpert about 2 years ago, and no experience on the Blue stuff apart from a MPPT used for the camping equipment)
What I like
- I did a DIY install and found it Quite easy to setup initially with AGM batteries and later the 7.4 SolarMd battery.
- I like to tinker and the option of having the RS485/modbus interface works great for me, so much that I hardly ever use the Sunsynk Solarman app anymore.
Monitor all parameters that you can see on the display, and storing this in influxdb
30s updates for key info with dashboards via Grafana
Can remotely setup and change some of the setting I have coded (just not done all of them but only the ones of interest to me for now) - Using the “grid peak shaving” setting to smooth out peaks - use the battery “spare capacity” for anything over 2.5kw load on total load (Essential + aux + non essential)
- Aux load works great: Have setup the spare geyser with 1kw element and Poolpump on the Aux load ,
Sunsynk control the “no 220v power” cutoff but does allow me to run even if there is loadshedding but sufficient capacity.
Node-red further control using the geyser and poolpump optimally when on 220v
What I do not like:
- The fan noise - not the loudest noise but definitely noticeable under load (have added a small 12v spare fan I had to keeps thing a bit cooler)
- Daughter complains of very high pitch “soft” type of sound when near the unit, but this is not noticeable to me and unit is in garage thus no issues to family and no complaints
