The battery is used alone, for 10 kW, and as in the link I gave earlier, the battery is connected directly to the inverter through a 200 A safety
Ok. So its not a current sharing problem between batteries.
There was also a warning about high DC ripple
Yes this usually happens with a battery disconnecting and reconnecting.
I (and others) will be keen to hear if the problem is solved with a lower charge voltage. Obviously none of the events are a good thing. A stable battery is a the heart of a all good inverter systems.
Since the system is remote, I will only be able to make all the settings closer to the end of the week, now the entire system is turned off.
Oh dear, that is disappointing. No vrm access? A remote reconfigure is possible so it the dvcc cap through the GX remote console over VRM.
After the MPPT controller failed, the user physically turned off the entire system and now it does not work at all. Also, to reset the error on the MPPT controller, you need to connect a 12 Volt power supply to it, and as you understand, this cannot be done remotely.
Does it actually give the error 38,39 or the error 80-88?
Error code: #80 - PV Input shutdown
- Errors 80 to 83: First disconnect the solar panels and disconnect the battery, then follow the reset procedure described here.
The system should be safe to power on using the battery, and inverter with GX to allow programming. Since it must be bypassed.
Obviously leave the solar panels disconnected with their breaker and the ac in and out disconnected with their breakers.
This will allow the system to be re programmed remotes without worrying about overcharge protections being triggered again.
But definitely do what you are comfortable with. After such an event it is good to physically check on the installation as well so that cannot be skipped.
This is alot of solar for such a small mppt, i know it technically doesn’t break the rules for input voltage or amperage input. It is just an interesting choice.i would have used a 250/100 personally.
The owner of the system, played it safe and turned everything off ![]()
The customer wanted such a controller because the other one was already more expensive for him, the entire system of 10 panels and a capacity of 4 kW fully fits the characteristics of this controller.
The difference in price between 250/100 and 250/70 is approximately 100 euros
Oh I had no doubt that was an acccepted config, i was just thinking of the loss of production, the power limiting you would be loosing 30% production almost.
Over a 5 year period (10 of it is a great installation) it would add up to more power lost than the initial 100euros of extra cost up front. And a wiser use of resources. I understand though manya customers cannot see past the ‘now’ cost.
But that is the beauty of a victron, what can the customer afford now - this - ok so its not ideal, but they need to be there so lets plan so they can build and add on until to the desired position for self reliance.
Stock on the power of the panels, based on the calculation of work in the autumn-winter period, to maximize the power on cloudy days
The MPPT reset procedure was successful. I had to abandon DESS, turned it off at all, there are a lot of questions about its incorrect mode of operation. The system should not work in this way, very disappointed, in the operation of the ESS mode!
