40W 12V Solar Panel Kit 60A/100A Battery Charger Controller Camping RV Caravan Boat
US$12.99 US$24.99

Q: I want to buy the regulator only, what the max Input volts I can use? I mean can I use an 28V solar panel for the 100a regulator?

REXX5000 you can buy the regulators(MPPT is what they are called for solar panels) with different voltage ratings and current ratings. so look up "MPPT" FOR SOLAR PANELS. and choose what you need. you will find them here on banggood too. hope this helps you out..

I am very disappointed with the market. The product I received has nothing to do with the descriptions on your site. I'm sorry I're not going to trust you again.

I received it after 5 days from CZ in good conditions. The system is functional with a maximum power of about 7 W (full sun, 17 June 14:00 1st image: Lead Acid Battery charge). At the panel dimension I expected less than 20 W anyway (0.1 sqM x 1000 W X 20% = 20 W). The open circuit voltage is 18.1 V (2nd image) and the short circuit current 0.54 A (3rd image), the temperature is about 50 degree C (4th image). The voltage-current and power-current characteristics were measured (with a constant current load - 5th image), the measurement at 0.5 A is visible in the 6th image. The controller current consumption (from battery or solar panel is of 12 mA). The controller disconnects the battery from panel at about 14.4V and reconnect it at about 13.5V, I did not notice the PWM operation. For small solar panels (like this one) it is a good choice, for higher solar power a MPPT controller would be more efficient. Overall I consider this a good deal (I bought it at about 30 USD); be aware that the solar panel power is less than 10 W.
