Battery charged indicator -- help!!

I'm trying to build my solar system with the raspberry pi, I bought the boards and connect them together and everything was fine, but I have couple of question, but before I start this is a quick pref about my system:

1-raspberry pi 3.

2-Suncontrol from switch lab.

3- Solar Panel - 330mA / 6V " shop.switchdoc.com/collections/solar/products/solar-panel-330ma-6v"

4-lipo 3.7v battery 1800mah "https://www.amazon.com/Lithium-Rechargeable-connector-Atomic-Market/dp/B07534KW8T/ref=sr_1_1?ie=UTF8&qid=1516526559&sr=8-1&keywords=lipo+3.7v+battery+1800mah"


so, when I run the test "testSun" it show me:

1-lipo_battery load voltage: 0v, lipo_battery current: 0ma

2-solar cell current: 0ma,

so, when the script switch from off to on or vise versa, nothing happen!!



My questions as following:

1- is it normal to give me this output result? why it show me the battery is zero volt!!

2-why it's not open the USB port when I run the test script?

this question not related to the sun control :

3-how to calculate the charging time for the battery?



hope anyone can help me with!!
