@AlexTZA Hi Alex, I’ve sent you a pm.

Good afternoon, @AlexTZA I am looking to replace my Sacolar 5kw with either a Sunsynk, Deye or potentially the Solis you have listed above. I currently have a Deichmann 4.8kwh battery. Does the solis have compatability to add used defined settings for the battery, or a general setting for lithium batteries, as my battery is not listed in the Solis’s manual. thanks in Advance Werner

Hi @RudShep, Very interesting article and fault finding. I currently have a Sacolar 5kw installed, all within specifications with a split DB(small loads), only 6 panels, so 3300W max at around 300V DC. AC and PV sides are on SPD’s so as safe as I can get. According to some internet research this inverter is the same as the Growatt 5000ES. My inverter has been back in under warranty twice in about 8 months. First for the high voltage spike you mention, and also picks up voltage on the AC side with no AC connected, only on the display and not really present. I also repeatedly get the error 02 with ambients being low and directly on startup eliminating the possibility of it actually being hot. I live in East London, and as the crow flies probably 300-400 metres from the ocean. Humidity can get so bad that my floors, bedding and clothes in the cupboards wet themselves. I am currently experiencing the intermittent fault number 2 again. And I could not reset it the last time. I did some fault finding again before stumbling onto your posts. I managed to get rid of the problem by isolating the solar panels from the inverter. So currently only a battery backup again. My inverter is still under warranty until January 2024, so I will contact the supplier in next week. Hopefully they can sort it out under warranty, if not where can I find specification of the components so that I can carry out the repair myself, as I won’t fork out for new boards if I can solder in some new components. regards Werner
