All-In-One Solar Power System
-Build a full size system in minutes-

MPP and a few other manufacturers now sell a "complete off grid system in a box" that has:
  • AC Inverter
  • Solar Charge Controller
  • AC Battery Charger
  • Automatic Transfer Switch (if grid power is available)
  • Circuit Breakers/ Temperature Protection/ Custom Charge Profiles
And they work! Instead of cutting/stripping/crimping wires for hours, and calculating fuse and wire gauge sizes, you can choose a package below and assemble it in minutes!

That is awesome! What is the catch?


Pros:

  • Cheaper than buying the individual parts and putting them together yourself
  • Takes minutes to assemble
  • Easy to program and can work with ANY battery (lead acid/ tesla/lifepo4/titanate etc)
  • Works with grid power! If your battery is low, or the inverter is being pushed to its limit, the solar box will switch over to grid power!
  • No need to calculate the requirements of your system, or safety devices. Connect some batteries and solar panels, change the settings, and you are done.
  • The DIY battery community has used these units 24/7 for years! They are extremely dependable. 

Cons:

  • ​High idle consumption. If you wish to have your inverter on 24/7, you may want to invest in a victron or xantrex (but they will cost 3x-5x as much money). Because the idle consumption is high on these all-in-ones, you will need at least 400 watts of solar panels attached to your system to offset the loss. If you do not plan to have your inverter on 24/7, this is not a problem.​

So loud fans, and high idle consumption. Not that bad! And for this reason, I am using a solar box to power my computer while building this webpage right now. They work really well! I have used one for 2 weeks straight, and the transfer switch works perfectly. I have done load tests on the inverter and pushed the MPPT to its max input, and nothing overheats and I like it!

Recommended Settings:

These MPP units have a lot of settings! You can go through each setting in the manual and set it yourself, or you can follow the settings that worked well for me below. Your needs may vary, but the settings below are good for most off-grid systems. If you have grid power connected, the settings will work great!

In my opinion, the most important setting is the "low DC cut-off voltage". This is setting number 29. You want this to be higher than your batteries low voltage disconnect voltage. 

Most lifepo4 bms cut off at 10.5-11 volts in a 12v System. So I will set the cut off on the inverter at 12v. This way, your bms will never disconnect power from your inverter. If you are runnig lead acid, 12v works well. Double this number for 24v systems.
