Description
Please consider Solar Charger Shield v2.2 as alternative product
 
The solar charger is a stackable shield to Arduino compatible platforms, enables adaptive battery power and act as energy harvester for in-field charging. You may use various batteries that has the voltage of 2.7V-4.2V to shift up for 5V output, or put on Li-ion battery and solar panel to form an autonomous sensor unit. The maximum current provided by the board can get up to 700mA. An USB connector is also useful to charge the battery.
 
Features
  • Short circuit protection
  • Battery status indication ( Red : Charging , Green: Charged )
  • 5V via USB port for powering small devices like USB Lamp, Cooler pads etc.

Hi, there are no need to add 20 solar panels to solar charger shield. One or two modules at most.

Could you guys please tell me what the difference is between this Solar charger shield v2, the energy shield, and the lipo rider? Like why would I buy the Energy shield over this solar charger shield v2? I know there are some subtle differences between

The low voltage of a drained battery seems to cause excessive current draw, preventing it from charging from a solar panel while powering other circuits.

There needs to be some sort of automatic load switching to prevent the circuit from draining

Hi, using a 6V 2W solar panel, sunny day, 1mA 3,7 Li-ion battery, and still the Vin pin never goes higher than 1.36 Volt. According to the wiki it should reach 2V in order to start charging the battery. What is wrong? Many thanks in advance

Thanks. What would happen if the voltage were to exceed this value? e.g. using a 7V solar cell. Is there over voltage protection/regulation?

Can this stack ontop of the Arduino Mega 2560, and still allow other boards to stack ontop of it?

Yes, it is. Sorry that we get the chip with official firmware and we do not know how to customized the firmware. You could refer to At command documentation, there is AT command for controlling the GPIO.

What is the switch used for? I don't see it listed in the schematic. Can the board function as a UPS, and automatically charge when solar power available, and switch over to battery/usb otherwise? Or do you have to manually switch from one to the other

Hi.You can switch the working mode of Energy Shield between “OFF” and “ON” via the working mode select switch. In “OFF” condition, Lipo battery doesn’t output but only pull current from any existing power source. In “ON” condition, the battery gets cha

Hi, I have 2 solar (2W(350mA) and 3W(540mA)).. I want to have more current but same voltage (5.5V), so I need to parallel the solar, so here the current will increase to 900mA. It is this solar charger can accept 900mA? What is the maximum current can
