Question 1

Can I run a well pump off this generator?

Accepted Answer

I connected this unit to my 120v 1/2hp Shallow well pump.  It works great!  This is one of the best improvements I've made in my emergency planning.  In fact, right now my power has been out for the last 4 days, yet I have running water!  I have a second unit that powers my refrigerator, pellet stove, internet and LED lights.  When the battery runs low on power, I start the gas generator, let it run for a couple hours and the battery is fully re-charged.

Question 2

How long can a fully charged unit last before losing it's charge. I assume one should not leave it charging constantly?

Accepted Answer

The lithium ion battery chemistry has a low self discharge rate. The instructions says to partially discharge and recharge it every 3 months. If it is used as a UPS (without ground), then it is plugged in all the time. It has a life of 800 cycles to 60% life so keep in mind that is a very low cycle life. When plugged in for UPS operation how the on-board control software cycles the battery charging is a question for the Manufacturer.

Question 3

I saw answer for updating firmware and is said via usb.  Who what where how do I find version and where to update.  Mine seems to be working perfectly

Accepted Answer

I would never mess with the unit that's working just fine

Question 4

My vans dc aux ports are all 15a, i know the ecoflow says 10a max, can i use my vans aux ports and only pull 10a? or will i fry the batteries?

Accepted Answer

Your question is not clear. If you are referring to charging the EcoFlow Delta from your vehicle DC power points (cigarette lighter socket) then the EcoFlow Delta will attempt to pull 10A from it. If your vehicle wiring is too small to maintain a high enough voltage at 10A the MPPT will adjust the charge rate or not charge. I plugged it into an 18A power supply set at 14.4VDC and it jumps around constantly from 1A-10A charge rate while the MPPT decides what it is doing. I plugged it into my vehicle both running and off and it did the same thing. I am not sure why, but I have heard it may be normal when feeding an MPPT from a regulated power supply. I need more information on that. In any case it has not exceeded 10A draw or more than 140W. I don't have solar panels to test it with or a higher voltage power supply.

As for batteries... if you are referring to your vehicle battery it will drain you vehicle battery until the vehicle battery reaches the MPPT low cutoff voltage (manual says 10-65V, but doesn't list a specific cutoff voltage). That low voltage cycling will damage your vehicle battery. If you are referring to the EcoFlow Delta battery that is controlled by the internal control board with built in protections. The EcoFlo Delta battery is much higher than 12V and requires a boost converter to get the correct charge voltage from either a vehicle.
