Hi we have an eco flow delta 2 along with a portable eco flow 220w bifacial solar panel, my question is can you use the eco flow solar panel to charge the leisure battery installed in our motorhome ? or do they only charge the delta 2

As far as I know they are a pretty bog standard solar panel. The solar input on the delta is also used by the 12v input so must be of a similar voltage (probably around 20v or so) you will need a regulator though as the regulator is built into the delta2 so can't be used for your leisure batteries. Although it could probably be done there are certainly more practical ways of charging your batteries.

Thanks for your info, we are about to get solar installed on the motorhome also, I just wondered if this was a possibility. We currently have 2 x 110ah lead acid batteries with an 1800w inverter which was already in the motorhome when we bought it. We are looking to go full time in the next 2 years so realistically how much solar would we need to keep these 2 batteries charged up. I understand that it depends on how much electric you use and how much sun etc, just wondered if anyone living full time could advise on our needs to be off grid for 4-5 days at a time. we generally use the delta 2 for all our phones, laptops, gadgets etc. Would 2 x 200w solar panels be enough? also looking to change inverter to a 3000w.

Yes ,you just need a compatible connection as the panel cables will be fitted with a plug that suits the ecoflow unit. But you will also need a separate controller for your battery as the ecoflow unit probably has one built in to the storage unit.
If your installing solar with 2 x 110ah batteries you would be better with 2 x100w panels as a minimum. But rather than lead batteries why don't you look at lithium, your ecoflow system is lithium also., or at least buy a controller that is lithium compatible and you could always use that for your ecoflow.

What do you use your current inverter for and what are looking at using your new one for and how much as most will say your 2 lead acid batteries won't last long with a big draw and in life if its frequent
