Battery solar Charge Controller 9v 12v 24v

QR78.00

Features:

1.A real mppt solar automatic maximum power point, intelligent tracking of charge management, low power consumption.
2.Scope: 1W-100W, 9V-28V It is suitable for charging 9V 12V 18V 24V solar panels to nickel-cadmium batteries, nickel-hydrogen batteries, lithium cells (batteries), wind turbines solar streetlights.
3.Input and output terminals are made of high-quality high-frequency switching power supply electrolytic capacitors with low impedance (low ESR), ensure the output ripple. It can effectively filter switching power supply failures.
4.Ultra low pressure designed to achieve low consumption and high efficiency, professional adaptation adaptation of solar panels.
5.Output voltage can be adjusted, automatic control cc-cw (can support single or multi-lithium batteries or lithium iron phosphate or lead acid batteries, high power LED, etc.)
6.charging current is set by external resistor (preset 5000ma/2000ma)
7. deeply depleted battery charge
8.Charging status and charging status indicator for LED
9.Solar cell maximum power point tracking, the output current is higher than the ultra-efficient current and real MPPT solar panel, support 8-28V, 100W solar power within the large charging current with a solar panel (recommended than each mould) several modules connect in parallel to amplify the charging current
Large current double diodes, high current efficiency constant resistance flat sense power inductor, low output prefect protection against reverse does not work, then end the damage against the charge sheet. 10A 10.the use of imported pipe double frequency low resistance mos,

specification:

1. input voltage: dc 8-28v(prohibition ac input)
2. Output voltage: DC 5-26V stepless.
(6v battery can be charged either 12 or 8.4v, 12.6. 16.8v lithium battery
7.2V, 10.8v, 14.4v lithium iron phosphate battery
string lithium batteries, lithium iron phosphate charging board 2-4)
3. output current: maximum load current 5A
4. Charging indicator: fast charging, long bright red, red and blue flash alternately charged. full auto stop.
5. MPPT function: automatic tracking of mppt maximum power point, maximize full use of solar charging
6. low pressure: 1v (as it is the step-down voltage regulator, the input voltage is at least greater than the output 1v)
7. Operating temperature: industrial grade (-40 ° c to 85 ° c)
8. Load regulation: ±1%
9. Voltage regulation: ±0. 5%
10. conversion efficiency: max.93%; Max: 95%, different lighting conditions vary.
11.Charging: intelligent automatic three-stage charging mode. Auto track solar charging current automatically adjust size.
12. No-load current: 3ma even weak morning sunlight can easily start automatically, eliminating manual switch.
13. Input reverse polarity protection: Yes. Exclusively designed low dropout prevention MOS transistor reverse polarity protection, reverse input does not work.
14. outlet backflow protection: yes. prevent night reflux battery electric charge sheet.
15. connection: there are terminals
16. MPPT voltage: adjustable, mppt solar modules in different voltage is different. MPPT control technology with load efficiency ratio control scheme sheet in general or a power mcu step down from dc-dc pwm the lift of about 30%. make full use of solar energy and low power operation. reduce energy loss.
switching frequency: 300khz PWM 17.
18. Size: 57x36x10mm
