I just got this today and I've been playing with it a little bit. I'd say it's worth the $28.

You plug it into com port with the provided cable. 1 plug. Simple.

Download the software from their site. iOs apparently has the software in the app store. I'd rather that android did as well. This removes a star IMO.

They have PC software as well on their site. From videos I have seen it's also compatible with a little tweaking with many other solar logging apps. If you're techno savvy it can also be bound onto your wifi network as a client rather than an access point but that's advanced. 

Connect to the wifi network eBox-WIFI-01 etc etc etc (it's an open network, more on that later)

Open the app and click wifi or ble. This one is wifi. From there there are lots of nifty bits of information, as well as timers that you can set for the load output, custom settings such as float voltage, max charge voltage, max discharge voltage, etc.

After playing with it a while I checked my daily Kwh production. (0.26kwh) the charge controllers display only shows cumulative Kwh production and only in tenths of Kwh. 

At this point I wanted to dig into the adapters web based software and customize it a little bit.

         !!!!!WARNING!!!!!!

Beyond this point you CAN and very well MIGHT do permanent damage to the device. "Bricking" the device and rendering it useless. Observe caution and only make changes to the access points web based software if you're 112% you know what you are doing and accept FULL RESPONSIBILITY for your actions. < / RANT >

Ok so as I have said the network is open. People like myself WILL want to see what sort of settings inside there that they can dick around with including possibly locking you out of it.

To justify my own paranoia and close that open door to even the most elementary hackers I decided that I HAD to password protect the wifi network.

So while connected to the wifi network what you will want to do is to login to the "gateway" which you can find in the android advanced setting or by using a port scanner.

In my case the gateway address is 11.11.11.254

I'm sure yours will likely be as well.

Once you open that page in a web browser you will be asked for a username and password. It's a pretty standard username and password used on lots of routers.

Username: admin
Password: admin

Now you're in. Turn back now or accept the possibility that you're gonna break it.

Click on AP settings tab on the left hand side of the home page.

Now on the AP settings page near the bottom you will see encryption is disabled. 

Click on the tab and select the available encryption. The protocols should be left to the default. TKIP AES OR TKIPAES. I left it on AES

In the password field set a password you WILL REMEMBER. If you forget it you're locked out.

Save the changes and you'll get a successful message click restart.

Now you'll notice that you're no longer connected. Go back to wifi settings and you'll see the network is now password protected.

Login using your unique password you created. It will work just like before except now it can only be logged into using a password. 

You might be tempted to change the SSID of the station. DON'T. The app will no longer work.

You might want to set it up as a client to connect to your wifi network. DON'T. 

Any other modifications are beyond the scope of this article. The purpose of this write up was merely to lock the front door before someone else did it for you and ruined your new toy.


This advice should not be followed BY ANYONE. 

You'll break your play pretty and want a refund. But alas you'll just have a plastic paper weight.

I had my doubts that would work but it did in fact. 

So it's a little less risky to password protect your adapter. That gave me a chance to take more screenshots.

Of course dont choose "PASSWORD" as your password.

In the illustrations it shows a master reset button at position#2.
 
Really weird thing happened. Earlier I checked in on my real time monitoring and it was in float and had generated 310 watt hours. Then I checked a little later and it was still in float and obviously the fridge came on because it was pulling nearly 40 watts from the panels rather than the like 8 watts it was doing previously in float. Now the daily power generated listed is 100 watt hours. Cumulative watt hours is still right on schedule. Just weird.
 
Which model Epever controller/charger do you have?

Can you change the controller's settings, such as battery chemistry, using the eBox?
 
The AN series 20a MPPT controller. And yes I can change the chemistry with the ebox, however the manual says that lithium has to be set to USER from iOs. There isnt a lithium option on the android app either but, I'm fairly certain lithium is an option from the OSD on the controller itself.

There are lots of options you can change in the advanced tab from the ebox app.


NOTE TO MODS
Idk if it's me but I've been getting MyBB SQL errors. Like a LOT. 

I typed this post within like 5 mins of the last post and was able to select all and copy before the server timeout.

I've been locked out ever since. Idk if it's just me or whatever.
