Ecoflow Alternator Charger 800W

[64 SPLIT]

I've recently installed the 800W Ecoflow Alternator Charger in my Highline Kombi to help charge my Ecoflow Delta 3 Plus. Haven't actually made the final connection to the starter battery yet as I wanted to check the alternator output on my van but can't seem to find any easy way of discovering what amp version it is! I'm assuming just reducing the output to 500W would be an advisable starting point though?

As you're a VIP member, ask @Pauly for your build sheet. It will list your alternator rating.

Standard alternator is 140A, updated it's 180A from factory AFAIK.

Dcdc charger is recommended 50% capacity, so 70A to 90A max depending.


Fyi 800w is around 65A (@12v)

I have a Kombi (180A alternator) with no plans of converting or adding in a leisure battery (both under seats filled with amp and sub) , but do have a FortyWinks bed in the back and use a driveaway/tent for camping. So biggest challenge when not on EHU was powering the vans stereo and lighting when in the bed. When on EHU I hook up a Victron Blue Smart charger to the battery to avoid it going dead. So when not on EHU power is a challenge. So initially bought a 160w foldable solar running through a Victron Smart Solar Controller but soon saw some drawbacks on less sunny days/evenings.

So after watching a few vids and some reading here, the new purchase is an Ecoflow Delta 3 + 800W alternator charger. Slot the Alternator/charger under the passenger seat to co exist with the stereo amp and the Delta between the seats for charging. This adds I feel a far better option to power camping things but also feedback power to the starter battery which will be powering the stereo and in van lighting. My thinking is the reverse charge should be employed to 'trickle charge' the starter battery when stereo and lighting is in use. Am I missing something? Any drawbacks for 'day van' use. I'll still have portable 160w solar for some stationary top ups and most days I'll be driving to/from somewhere to top up starter and the Delta 3.

The theory sounds good. Essentially you are powering you 12v system (lights) from the starter battery but keeping they topped up from a power station?

Just be mindful of the cable you need from your power station to the Alternator charger.

I thought I needed and bought an XT150 cable which is not compatible with my EF D3 Max Plus, I have queried this with EF and they replied back to me telling me I needed the XT150

I actually need the smart generator cable which is much more expensive or an even more expensive adapter.

I assumed from reading EF website the 800w was compatible with all Deltas with included cable? Off to double check now.

Yes confirm it has the correct cable that supports reverse charging. On my EF the extra battery power is an odd 4 sided shape, with mostly 4 big pins and a bunch of little ones in the middle, the XT150 cable plug is about half as wide as my socket and only 2 big pins.

Sounds like you have the Delta Pro cable. This is the shape for my Delta 3 and also Alternator / XT150. I should be good

Yes that's the cable I have, EF take a week or more to respond to an email

This is a perfect use-case. There is one tiny shortcoming, and that is that you will need to _manually_ manage the Alternator Charger's "Mode". When you are driving, and want the Delta to charge from the alternator, it will need to be set to Charge Mode, and when you are camping, and need the Delta to send power to the starter battery, you will need to set it to Reverse Charge or Maintenance Mode. Reverse Charge and Maintenance are virtually identical except that Maintenance has a limit of 100W, and Reverse Charge's speed can be configured in amps in the app.

The cable that comes with the 800W Alternator Charger is already the right cable to connect to a Delta 3 [Plus].

Installed the alternator charger last night. Took 3.5hrs. Passenger seat and seat base out so I could run cable from there, under the floor lining, over the front near side wheel well. Used the upper grommet through the firewall which comes through right behind the battery as the stereo amp power cable was using the lower grommet and no way was going to cohabitate the Evoflow cable. Had to drill a 22/24mm hole in the metal plate behind the battery and hook it up. As the charger sits under the passenger seat, the cable is in an easy to use location to keep the Delta 3 between the seats. That makes it easy to adjust settings on the unit or the phone to manually manage charging/maintenance modes.

Went for a drive today. Delta 3 was at 80%. Charging seen was maxed out at 150W. Not sure if a setting is limiting that or if the charging has been throttled back as the Delta was 80-90% charged. Charge to full was estimated at 1.9hrs, higher than the quoted 1-1.2hrs by the Ecoflow blurb. Will need to check that out further. Car charging current is at the max 76A from memory.

Looking forward to a trip out and use in the field.

This should work well. I've got the 800w charger connected to a delta 2. I run mainly the interiors cargo lights( led bulbs )and sometimes the radio using maintenance mode. Although the battery seems to handle the led light anyway without maintenance mode. Charger sometimes dips below 800w because of the smart alternator but apart from that it's very reliable. Sometimes bluetooth doesn't connect for switching between modes. Overall excellent, i run a diesel heater from the delta 2 using an ac/dc transformer. The dc port on the delta 2 can't handle the starting surge.

Just reading this....whats your ac/dc transformer set up...im keen to do this too. Cheers.

I've got one of theses connected to an autoterm. https://www.amazon.co.uk/dp/B07CWFS...e=cm_sw_r_cso_cp_apin_dp_03KVZCDCRY7RF80GRJFS
It could go to a 12v fuse box but i've connected it straight to the heater.
All under the drivers seat, for a basic setup until i can decide what else to do, it works a treat.
The ac/dc has a normal 3 pin plug and plugs into the ecoflow so the ac handles the surge. Other options now are the Bluetti which has a dc port that can handle the higher wattage.

Interested to know if any of you have adjusted the starting voltage for your charger? I've tried dropping mine to 12.5V but I'm still finding my alternator charger doesn't switch on by itself when I start driving and so consequently doesn't charge up my Delta 3!
I have to manually press the 'on' button on the charger's dongle each time (which is a PITA cos it's in the back of the van so not really convenient).

 

[Dannyb6467]

I've set my voltage to 12v. I had and sometimes have a similar problem to you with needing to manually switch on the charger. It happens rarely now though. I updated the firmware on the charger, I set the discharge limit on the battery to 10% too. The charger seems to need a bit of life in the battery to operate??? Also, switching on can be done via the app so i dont need to access the actual unit. The goggle does stall though and so that's confusing. DM me for a call if you like as mine hasn't been straightforward at all but it seems to be settled now.
