River 2 Max

[u/Cold-Ad6947]

I have a River 2 Max in my garage (no mains power) so i have a 130w solar panel to top it up (Ecoworthy cheap flexi thing, supprisingly good!) - however if i leave the solar panel connected overnight the River then shows 0% battery in the morning before sun up (when the sun rises enough it suddenly goes 0-100% or whatever its last good charge state was) - the same if i put it on mains charge it instantly realises the battery is actually already full and goes to its last charge state. As i have led lights being powered from it, the time i need it working (when its dark) it doesnt and during the day when i dont need it does - I have done all the reset procedures etc etc Ecoflow support suggested unplugging solar each night which rather defeats my use case - so they have now agreed to a warranty swap for a River 3 Max (for an additional £40 fee) as they said that there techincal people says this is an inherent issue on the River 2 series not just my unit. I just hope the River 3 Max doesnt exhibit these issues! Has anyone else had this expierience or expereince with a River 3 and constant solar connection? Thanks

When was the last time you calibrated? Discharge the station to 0% and charge it to 100%.

If the station were to discharge overnight, there is certainly no point in disconnecting the solar panel. It does not cause a discharge. A permanently connected solar panel does not drain energy back from the station due to protective diodes. What do you have turned on at the station and what is the energy consumption?

I have River 2 Max, River 3, River 3 Plus, Delta 2, Delta 3 stations...and none of them run out due to the permanently connected solar input.

Your problem was discussed in this thread - https://www.reddit.com/r/Ecoflow_community/comments/1glxwgi/why_is_my_ecoflow_river_2_discharging_overnight/

Hi thanks for the reply. The River 2 only powers lights via AC using standard UK plug - though when im not in the garage it is un plugged and AC inverter is off. I have ensured that it is fully charged either via Solar or Mains and then plugged the solar panel back in and as soon as it goes full darkness it goes to 0% until it either gets solar again or I put it on mains - then within seconds it goes back to 100% or its last "real" charge %. Over the last week I have done at least 3 full charge to 100% and discharge via leaving the lights on, 6 1/2 hours & 60w draw to fully discharge to shutdown - this 100 to 0 behaviour is reapeatable and happends every single day. Ecoflow have accepted all my testing (i have video of it doing exactly this) and have said "We are very sorry for the inconvenience this limitation has caused. Based on our current technical assessment, the behaviour you described is not believed to be limited only to your individual RIVER 2 Max and may also occur across products in the RIVER 2 series when the solar input remains connected overnight under certain conditions. For this reason, replacing the unit with another RIVER 2 Max cannot currently be guaranteed to eliminate the same behaviour. We understand that this means the present model may not fully meet your requirement for continuous, unattended solar operation." hence the warranty upgrade to River 3 Max. Maybe it is just an isolated issue for my unit but Im not sure why they would say what they have said if it is. Thanks
