This is exactly the patch I use. It works perfectly for me.

I use 264.62 and I have no problem with charging from a 145 amp photovoltaic system. I haven't tried it on the grid because I'm completely off grid. My inverter looks like this, but it's still a copy of Voltronic. I've also uploaded the patch to a few other inverters that look like this and their charging current is over 130 amps. https://www.panpowersolar.com/products_details/19.html

Hi CJB. The latest patch, I think it's 64.69 and it's uploaded a little higher in this post, but I haven't tried it and I can't tell you how it behaves. Otherwise, I'm sure about patch 264.62, because in addition to one of my inverters, I've uploaded it to 15 other machines and they all work great. Instructions for uploading the firmware are in the other forum, and I downloaded the firmware from here. Read the instructions carefully and be careful not to mess with the cables. Good luck! instructions-PIP-5048MK inverter - Page 20 - AEVA Forums I recommend you also read this topic on the forum-Firmware Axpert Max Twin 11K - Page 5 - Inverters - Power Forum - Renewable Energy Discussion

I apologize for interfering, but I have direct oversight of this particular firmware. On one of my inverters I had factory firmware 64.03 and I had the problem with it getting stuck at 90 volts. I uploaded patch 264.62 prepared by @Coulomb and since then the inverter has worked wonderfully. The MPPT controller starts as soon as the current passes 0.2 amps and the yield has increased significantly. I charge the batteries from solar energy with 145 amps. It also works great in cloudy weather. I have uploaded this patch to several inverters and everything is fine. Be careful with the cables when uploading the firmware. Good luck!

Today I decided to try a different way. I turned off the power supply and discharged the capacitors. I ran it only on the city network and with a simple old telephone cable I connected the laptop to the inverter display. I ran only on the city network and while it was counting the seconds I gave it an update and it started. Everything is fine now, everything works with the patched firmware 278.09. Thank you very much for all the patched firmware you do. I appreciate it. I have repaired the MPPT controllers of quite a few friends and acquaintances. Thanks again!

Hello, young people! After several updates of friends and acquaintances of Easun inverters, it's time to update my Easun smw11 kw inverter. My first one was with 64. 03 and I updated it with 64.62 and it works like a clock. However, the second one is 78.09 and the MPPT controller does not wake up and I decided to update it with a patched firmware too, but by mistake my daughter pulled the cable and accordingly stopped the update in the middle. Now it flashes 32! and it doesn't work. It doesn't let me reflash with the cable in the kit. I try with a USB flash drive, but it says error 003 (wrong format). Could you advise me how to proceed?
