pHi All
have now been back to customers house, further investigation without touching the system has revealed.
BMS Comms Fault on SP2000 unit. (left as is due to the complaint being lodged)
no paperwork of any sort apart from the invoice / contract & a lovely brochure showing PV installtion process but no mention of battery systems.
so no user information
no user warranty information
no instruction manual that came with system i would think
basically nothing
terms & conditions on the back
no more than 25% taken as deposit but had to pay in full on day customer has cheuqe stub & signed invoice / contract
what is quite noticeable is that on the invoice / contract it says SOLAX not sp2000
customer also informed that the company had setup the monitoring side & would monitor from their end should there be any problems.
I managed to set them up on the Growatt site as a new user on the system but there is no storage information for the system no records just flat line no charge discharge of the system. I will speak with Growatt on Monday see if they have any records of the system & if so could they email any data to the end user.
also mentions on the invoice just above customer signature box
binding contract. sign only if you wish to be legally bound by them.
it also just above that mentions about the deposit & rest to be paid in full upon completion to their senior installer on the site.
also that I wavier my 14 day cooling of period.
bit more about system was 10 & 6 split on system.
