Hello Dears,
I have a problem with an Easysolar 1: it won’t start! A week ago I turned it on and it worked, then I turned it off (I use it at a holiday home). Today when I wanted to turn it on, after pressing the “ON” switch, it didn’t want to start anymore, nothing on the display and no LED on the display light up. (dead). What could be the cause?
Battery supply voltage is 49.8V. The main DC fuse is OK. I mention that I don’t have panels to charge my battery, but I was using a generator with which I powered the AC and charged the battery and only used the inverter overnight. Please support.
Check the fuse?
The main fuse is OK.
Is there any other fuse somewhere?
No the one by the battery terminal was the one i was thinking of.
It could be the low restart is set at a higher voltage here.
Do you have lead acid or lithiums?
the battery is Lithium (dyness 5kWh).
Another time when the battery was discharged, it would start and give me a warning message, but now it’s completely dead? and without it starting I have no way to charge the battery. I’ve never had anything like this happen to me before.
Do you think I could connect the computer to the bios and rewrite the program even if it’s dead?
If the battery is on and output voltage is there, try unplugging the gx.
The unit needs to be powered on to program it. If i am not mistaken dyness uses 52v for restart.
Does it still power on from the grid input side?
The battery is on. I have voltage in the inverter (at the terminals, even after the main fuse) 49.6V. I have mains voltage connected to the inverter from the generator. Another time it also started with a voltage of 47.5V. Only now it is dead. and I asked the community to see if you have experienced something like this before and what is the remedy.
I really made a wrong choice with the Dyness battery because its maximum voltage is only 53.6V (before buying I couldn’t find any data about the charging voltage. It was only after I received the battery that I received the manual from it). But the discharge goes up to 48V.
I have a “grid” for nothing, because until it sees the Victron and decides it needs to charge, it doesn’t connect to the"grid". 
Do you have a GX? Is it powered up?
Is the front rocker switch in the right position?
Yes, i have GX, but it doesn’t work either. is powered internally.
I pressed both the ON position and the Charge position and nothing.
If the gx is not powering up, and the fuse is ok then there is no power from the battery. (Or the GX fuse is blown?)
Of you are certain the battery is powered up and providing voltage, then try unplug the ve bus and switching on the inverter with the front rocker.
Thank you LX for support.
Today I identified the problem in the installation: the color control GX was short-circuited.
After disconnecting all the equipment from the DC and the communication bus, thus individually powering each equipment, I realized the defect.
What is unclear to me is: why was no protective fuse placed on the control power supply of each device?
Maybe in the future the manufacturer will read these problems from the community and take corrective action.
Thanks community!
