Rictronics Gracias Adi por el análisis

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.

Q: Después de un tiempo, la batería no carga, cambie cargador, cambie batería y nada. No recibe carga y el indicador de carga está seco. Creo que es el Regulador interno, pero no se cual es. Alguien me puede ayudar con este bug?

parece usado.... no sé, traía restos de la protección que llevan algunos metales, un plástico azul sobre los electrodos y restos de haber sido limpiado. con lo del covid uno está cada vez más sospechoso de todo y observa con mayor detención... tal vez por eso estaba muy barato
