Neego raspberry pi 4 screen case for raspberry pi monitor touchscreen display 7 inch.
A solar panel battery charging monitor using a raspberry pi 2 connected to a maximum power point tracker mppt and a raspberry pi 3 showing the output graphs and data.
The voltage readings are sent to a raspberry pi where you can plot them set up alerts send them over the network or do anything else you want.
As you might expect this battery pack can also double as a smartphone or tablet recharger.
This sort of thing has been done many times before but you might find my approach interesting.
Compatible with raspberry pi b and later two usb ports let you power your pi and a display.
This project monitors the voltage and indirectly charge status of a 12 volt lead acid battery e g.
Therefore you can also supply the miniioex with 12v battery voltage instead of 24v.
For low power projects you can reduce the amperage quite a bit before it affects performance or stability.
The 12bit analog input sensor on the miniioex is also connected to the 24v and 5v line.
I m setting up an off grid solar solution and the mppt controller i purchased only supports modbus via serial.

Had i spent an extra 200 i could have got the next model up to.
Earlier models demanded a lower draw of 5v at 1a but in practice greater amperage is usually preferable.
The way to do this is to monitor the battery voltage if you can monitor the battery voltage when the battery will run out you can replace the battery with a spare battery.
Shipping with a case that can be attached to your pi this 4000mah battery outputs 5v.
The pi 3 has a recommended power supply of 5 1v at 2 5a which covers most situations.
