Tiny off-grid solar inverter


This one has PWM charge controller MPPT will be better but it just needs one 12v battery.

Maybe this
Edit I see its simulated sine though.

 
Yea the inverter gets connected to grid battery and panels
Edit it will use eskom and switch over to batteries if you set it that way
Or be in solar mode ie focus more on power saving but the battery may not be full all the time as the battery wil supplement when shading occurs or low light conditions



And can then connect ecoflow to it to charge as a backup

The ecoflow has panel capabilities?
why not just connect a panel to it

And use it as you backup device ,or is it missing functionality that you want to get another device for ie ups
I want the main power source to be solar.. I have the ecoflow, so I don't want to spend money on a battery.. 6.6k for a lithium battery can cover just about two solar panels instead..

Two 550watt solar panels, each with a micro AC inverter pushing to a ATS, that also has grid power connected on the second input, with the ATS then outputting to the ecoflow, seems to me would provide for a reliable source of power, while having solar be the main power source as and when there is sufficient sunlight..?

Running plain solar not gonna work even if you have 1 000W of panels.
One cloud and bye bye power. You need a battery buffer.

Also for the price of those Micro inverters you may as well get a PPS that can do both, put Solar as primary and have the bigger solar capability.
 

Micro inverter up to 2000w

Can connect the ecoflow to it too to charge so you can have backup power

If too little sun

You can get output on cloudy days too just a portion of normal capacity

You can connect panels series and start with maybe 2 and later add 2 more if needed

If it goes south you have no option of adding a battery though

While if you get an inverter that can run on solar only and has a battery connection

You can Later add a battery if the experiment doesn't work

Though i am fairly certain it will work

How many panels you will need , is the thing

ie cloudy doesn't equal no power just a lot less , a decent enough array can carry load

ie know a buddy of mine was even mining with excess power on cloudy days

he had 3 rigs but could only run one rig on rainy day
He does have a 12 panel array though

From what i see the axpert high voltage mppt models can run from solar only

if the firmware is more recent version

On this thread

Do see.mention of system shutting down morning and afternoon due to low light
Depends on the load though
ie the falling over happens if load overshadows solar
So may find you need big array

So buying toi small a solar controller can limit the experiment if you hit the max before attaining stability

Panel or 2

2.2kWh usable should crack 7hours on your 300watt usecase with no sun
