I have a 24V (25.6V) 100A LiFePO4 battery and an EcoFlow PowerStream, and I want to charge it with two solar panels, using a Victron MPPT 100/30 in between.
The specifications of the solar panels are:
• 425 Watts
• 132 Cells per panel (6×22)
• 1722 x 1134 x 30mm (LxWxH)• Module efficiency: 20.53%
Panels of 425W might do 425/24=17,7A (not in your specs), so putting them in parallel would give more than the 30A the MPPT 100|30 can deliver. Putting the panels in series will do fine.
It looks like he power stream has an internal battery, and is designed for external solar modules.
The internals are probably not designed to cope with either an external battery or external charging other than the supplied modules, so it would not be recommended to modify this kit.
However, the two solar panels you have, wired in series will charge the 24V battery - but you do need to check that the max permitted charge current for the battery is > 30A.
If you were thinking about using the output from this battery to charge the EcoFlow, then you would want to limit the current to that provided by the EcoFlow solar modules. Again, doing this may not be safe or may cause damage to the EcoFlow.
