ISolar SMW 8KW firmware update - MPPT under sub 92 volt

Am pus recent (luna decembrie 2022) o instalatie cu panouri fotovoltaice, inverter EASUN 8 Kw cu 2 MPPT x 4 Kw, 8 panouri JA Solar de 545 W (49,5 VOC / 13,7 ISC) si am avut neplacuta supriza sa constat ca pana in ora pranzului, ”productia” era foarte slabă. Tensiunea panourilor la intrare in MPPT nu depasea 95 volti cc. In gol masuram in jur de 380 V CC, dar cand puneam panourile in sarcina scadea si se mentiunea undeva in jurul valorii de 95 V cc. După ceva discutii cu colegii de pe grupurile de fotovoltaice, un coleg care a avut o speta asemanatoare, m-a ajutat cu un upgrade de firmware, spunand ca de fapt problema e din inverter, din cauza unui bug de soft. In aceste filmulete va prezint, in timp real, cum am facut acest upgrade de firmware. Recently (December 2022) i have installed a system with photovoltaic panels, EASUN 8 Kw inverter with 2 MPPT x 4 Kw, 8 JA Solar panels of 545 W (49.5 VOC / 13.7 ISC) and I had the unpleasant surprise to find that until lunch time, "production" was very weak. The voltage of the panels at the entrance to the MPPT did not exceed 95 volts DC. With no load, I measured around 380 V DC, but when I put the panels under load, it decreased somewhere around the value of 95 V DC. After some discussions with some forum”s mates, from the photovoltaic groups, a colleague who had a similar problem, helped me with a firmware upgrade, saying that the problem is actually with the inverter, due to a software bug. In these videos I show you, in real time, how I did this firmware upgrade.
