Hello all, it worked till now, suddenly not anymore.
I have 100W solar panel and Lifepo4 100amps 12V connected to the MPPT 75/15.
From there I go to a blue sea fuse block from where I power an Ecoflow River.
New Problem: The mppt charges my Ecoflow Powerbank ONLY with solar power. When the sun is gone, it does not charge anymore … totally ignoring my full Lifepo4 battery.
In the past, when there was no sun, the Ecoflow was charged from the mppt routing power from the battery.
Is this a hardware problem or did something change in the app settings?
Is your Ecoflow (?) connected to the load output from the MPPT?
you can check the output state voltage and current of this from the Victron Connect ap. Post the results if you still have problems.
yes you can upload files or vids:
use the icon with the up arrow ^ next to the bullet list icon.
it may be possible that you have been drawing too much current from the load output. This is not meant for charging batteries with. You can also edit an existing reply to save adding another …
See beside installation schematic. Very simple thing.
The MPPT 75/15 should charge the battery from solar cells and feed the Ecoflow Powerbank directly from solar cells when sun is delivering power and the battery full.
!! However, when the sun is off, AND I need to recharge the Ecoflow Powerbank, then it should charge the “Ecoflow” Powerbank from the battery, right?
No, the load output is using battery voltage, not PV voltage. For example, if the battery is charged to 14.6V then thats the max voltage you are going to get on the load output. It will switch on/off at whatever settings you set in the VictronConnect app, this does not necessarily need to be only when the battery is fully charged.
Also note that the load output can only deliver 15A and does not like inrush currents. If it switches off due to inrush current, it will not tell you anywhere why it switched off, the only thing you will see in the App is that the load output is off
The Powerbank is only charged with sun is shining! When I cover the solar cells … there is no power delivered to the Powerbank … despite having a full LiFePO4 at 13.7Volt connected to the MPPT 75/15… what is the problem?
Have you checked the fuse in the MPPT. What size is your fuse to the ecoflow. Post your load output settings by grabbing a screenshot in VictronConnect.
I think you on to something - I have not realised that there is a fuse in the mppt. I am traveling but will check this soon back home this we. I let you know!
