Yes I bet they would be a decent unit, not seen them before, Tigo very similar to these in functionality and form.

Thanks for the article, interesting, I luckily have the equipment installed to allow updates, and my units are 2023 versions, Tigo engineers have been on my system many times with my parallel issue. Since yesterday , I heard back from Deye inverter people, as expected, the inverter unfortunately changes series connected strings to parallel! That's the issue for the optisers.

Yes all panels are in series with each going through an optimiser, then suspect they go parallel when meeting in the inverter. Tigo install image attached https://assets-global.website-files.com/5fad551d7419c7a0e9e4aba4/600ef20aa9acd8bc2a054520_Quick Start Guide - TS4-A-O.pdf

Hi, each panel has an individual Tigo optimiser, the inverter image shows how the panels connect, I assume that on one mppts the 2 strings do somehow link inside as there is now less amps on the readout. This is the manual. https://www.deyeinverter.com/deyeinverter/2020/12/29/502012022【a】储能单相说明书sun-5-8k-sg01lp1-useu-ver2.0-deye.pdf Many thanks

Hi everyone, On the deye hybrid 8kw, there are 2x mppts with connection for 4 strings. I have 4 strings in series into the 2 x mppts. When wiring 2 strings in series into mppts 1, do they connect internally together? Which would make them a parallel connection? Reason I ask, Tigo optimisers tech help tell me it does turn string into a parallel connection, there by allowing unwanted reverse DC voltage to interfere with the optimisers!! Because of this, I put 2 strings into 1 string into mppts 1 but noticed that the voltage went higher and the output dropped lower! I was also wondering if I installed a blocking diode on each string after the isolators if that would cure the issue assuming it is coming from tge inverter. Any knowledge of this would be grateful. Thank you

Good morning, I am having trouble getting the same type of cable connector as Derek Ramos picture above, in the UK, can anyone help me please?
