300 V
300-volt-100-amp-meter-for-solar-panel
$2 for 5PCBs - order with coupon code: JLCPCBcom
Any questions about JLCPCB or ordering, pls email support@jlcpcb.com
Bought a cool-looking voltage and current meter for monitoring solar power usage in the shed. It can handle up to 300 volts, 100 amps and displays volts, amps, watts, watt-hours, amp-hours, time, temperature and more. It's powered by the solar panel so it's always on during daylight. An easy-to-read backlit LCD shows all the data you need. Costs about $25.

PWM S
pwm-solar-charge-controller
The controller is regulating battery voltage now. Target voltage has been set at 14.2 volts. The display LED shows a PWM simulation when target battery voltage is reached (this doesn't show up too well on the video), and a series of flashes when it's below target voltage. 1 flash for 11 volts, 2 for 12 volts, 3 for 13 volts etc. It also shows a series of rapid flashes if voltage drops below 10.5 volts.
The LED can be turned off altogether if desired to save power. With the LED turned off, the controller takes very little current - about 0.5 milliamps, that's just 500 microamps!
Future developments will include detection of excessively long cables between the battery and the controller or excessive current flow. Also voltage measurements will be more discriminating to get a more precise, more stable feedback control.
