Wizard Green Solar, Stay away !

After me paying good money and showing a lot of patients, Wizard Green just abandoned the project and left me with a nonfunctional installation! They could never sort out the Lithium battery - Inverter communication. This caused the output voltage to be unstable. This resulted in lights flickering, garage door malfunctioning, etc. At a late stage, the low voltage inverter was changed to a high voltage type. Instead of re-wiring the solar panels properly, they decided to only connect 8 of the 12 panels. All of this without informing me... The rest of the wiring was done well. For that I generously awarded two stars
