Cosa dovrebbe prender fuoco? Il silicio delle celle o il materiale con cui sono laminate? Il circuito del controller sembra di buona qualità:
1. Applicable to various types of batteries
2. MPPT function
3. Microprocessor controller pulse width modulation (PWM) charging
4. Temperature sensor battery charging compensation
5. Overload protection (automatic restoration)
6. Overcharge protection
5. Short circuit protection (automatic restoration)
8. Thunder protection
9. Reverse discharge protection
10. Reverse polarity connection protection (automatic restoration)
11. Under voltage protection
Rated Voltage: 12V/24V
Max Load current: 20A
Input voltage range: 12-40V/24-80V
Overcharge protection: 17V/34V
Full charge cut: 13.7V/27.4V
Low voltage cut: 10.5-11V/21-22V
Temperature compensation: -3mv/°C /cell
No load loss: #8804;20mA
Max wire area: 4 mm2
Ambient temperature: --25°C——+55°C
Dimension: 193 x 110 x 48mm
Poi l'hai detto tu stesso.... fanno tutto loro comunque ;-)
