Does what it's supposed to do
I have an Eco Flow Delta 2 Max and 2 smart batteries, I decide to purchase the refurbished units, after being reassured that they have had almost no use. Certainly the units looked new and perfect.
I have added more panels and a Power Stream unit too. Firmware updates without a hitch. Units give full capacity. Effortlessly power a 2 kW fan heater for my workshop, we still have chilly mornings even in May in South of UK, gets down to 3C in workshop.
Also has been running base load of house via the power Stream when heating not needed, can provide up to 800W from panels helped by battery if necessary.
I see no reason why it will not last the claimed 10 years use, very well built and has loads of protections built in, so I have no safety issues to worry about. The only downside is that one of the battery ports is taken up by the power Stream, would be great if some kind of adaption was possible (can't have everything can we).
I will do a further review in a year or two and update again.
I love it!
Purchased the extra battery to go in our campervan, added with the smart Alternator charger it is amazing.
I have not had to charge either battery up via mains since installing.
Purchased a delta 2 max, extension battery and alternator charger these have transformed my working environment allowing me to replace my petrol power generator!
Bought q main unit, second battery and folding solar panel for my boat.
Connected and charged very quickly using mains at home then tested with some appliances and topped up with the solar panel. all good. Excellent build quality, super info displays and plenty of USB sockets and the like.
Well thought out. Very happy.
