Not Happy

Since 2021 I have been a supporter of Growatt. I had a Growatt SPF5000ES linked to Pylontech US3000c batteries. The solar system has worked well, until last week. Code 05, code 08, code 04. Now I am hoping someone at Growatt EU reads this review. I have purchased not only the SPF5000ES but the 5000es (to replace spf and allow further diagnostics) and the 6000es Pro. The 5000es has caused issues because coms won't communicate. After 50 calls, mails etc to Growatt, Pylontech , distributors.. no one so far seems to have a solution. Eventually today it transpires that perhaps the firmware is causing issues...firmware? So why is this not shown on distributors Web pages? Why do Growatt SA have a telephone number if no one answers? Why as the end user must a person run around for 48 hours trying to find a solution when CPA clearly states an OEM obligation in South African Market. Lastly, and I realise this is a public site, surely in this day and age South Africa has the required expertise....so why does no one know? I am led to believe that lithium batteries are explosive, that bad (I think it's called) coms instructions can result in damage and yet Growatt seems ok with this? They must be, at 9, 9h30, 10h30,11h01 messages were left for technical assistance. Wake up guys, the product can be good but if distributors and aftersales sucks then in reality what is the product actually worth? To close, today after another 23 calls I sit here with a non functioning system. Inverter 1 day old. Spf on its way fir complete assessment. 6000 series sitting in box as I am thinking that actually installing it may just cause problems...... so Growatt....where to from here? Should you be kind enough to attend to me as a client I have no issue updating this. However I will not hold my breath.
