Title: Solax invertor and Save Heat and Energy
Post by: agw53 on January 04, 2017, 06:21:38 PM
Had a new system installed in Feb by Save heat and energy ltd . A Solax inverter was fitted.
Before Christmas the system went into fault mode. ''DC INJ FAULT'' and has not worked for 2 weeks.
Have a 20 year warranty, but Solax will not talk to an end user. Save Heat and Energy say they will get an electrician out when thet see his diary.
I could do without the stress of this,Antone got any ideas, Please bear in mind that I am not an expert or an electrician. I just want a system that works
Thanks

Alan

The fault mode is described as "DC component over rating in AC output" which is not very helpful unless you have a detailed understanding of what the Chinese engineer was trying to express when writing the original manual before its translation.

I fear you will have to wait for them to send their staff member.

Right now you wont be generating much anyway lucky if you get 20p a day so I wouldnt worry about it.

That all depends on each individual day. Over the holiday period, my generation has seen days less than 0.5 Kwh and 2 days over 8Kwh albeit from 6.5Kw of panels. Winter can still throw up the odd reasonable output when the skies clear and I would have hoped the installer would have been more helpful.

Have you tried 'switching it off-then on again'? Just switch the AC isolator off for 30seconds-then on again.
