產品介紹：
MPPT30控制器是一種智能型，多用途太陽能充放電控制器。該系列產品使用訂制的LCD顯示屏，具有非常友好的操作界麵；各控制參數可靈活設定，充分滿足您的不同需求。
MPPT30具有如下特點：
1.MPPT功能：本控制器特點在於智能調節太陽能發電板的工作電壓能跟蹤太陽能板發出最大電流，使太陽能板始終工作在V-A特性曲線的最大功率點。比較普通太陽能控制器，對太陽能板發電功率的利用提高瞭10-30%；
2.形象的LCD圖形符號，簡潔的按鍵模式；
3.帶自動溫度補償的智能型PWM充電方式；
4.可調節的從放電控制參數，可設置的負載工作模式；
5.蓄電池反向放電，欠壓，反接保護等各種保護功能
一:Product introduction
Solar LCD series a kind of intelligent, multi-purpose solar charge and discharge controller
LCD screen display | Battery reverse discharge protection |
Easy operation interface | Battery reverse polarity protection |
MPPT+ PWM charging mode | Battery under voltage protection |
Parameter user can reset | Overload, short-circuit protection |
A key to open and close the load | Automatic temperature compensation function |
A key to restore the factory settings | USB 5V charging (for 500mA) for mobile phone |
二: Installation Instructions
Installation
① Ready Qi installation tools and materials, and cable. Please matching suitable cable
② Ensure that the current density <4A/mm2 this will help to reduce the line pressure drop.
Recommended: 30A current 10mm2 Check whether the installation site,Comply with the relevant safety requirements, avoid
damp, dusty, there is easy
Inflammable, explosive and corrosive gases place to install using the controller
③ Install the controller fixed to the vertical plane, see Section V mounting aperture and hole spacing. In order to ensure a good controller cooling conditions, the controller on the bottom of each reserved 10cm space
|
④ As shown on the right wiring sequence: load, battery, solar
Battery plate is connected to the controller to be taken to ensure that the load, battery,
The polarity of the solar cell panel and controller
⑤ Before use: external temperature sensor probe into the left of the controller temperature probe interface probe placed in similar battery temperature. (Line extension must be built-in devices of the external temperature probe coextensive Otherwise, the controller will control parameters of the temperature compensation of the error
⑥ Warning: In order to prevent accidents from occurring, install: non-professionals can not be engaged in loading and unloading operations
三LCD operating interface description

LOAD ON 1 H---23H Load control (1 hour --- 23 hours can be set) | |
LOAD ON 24H 24 hour -is normally open state | |
0h-light control mode, power supply load after dark, closed after daybreak the load 24h-represents a normal mode, in the case of no fault, the load is always in the power supply state. 1h ~ 23h-light control delay mode, after dark began to power the load, and delay to set the time to close the load. | |
Charging current | Discharge current |
Voltage charging station (can be set) | Undervoltage protection voltage (can be set） |
Temperature display (around the probe) | Undervoltage recovery voltage (can be set） |

四 Common fault with processing methods
Battery under-voltage protection | Battery normal power supply
|
a) Undervoltage protection and handling: screen display as shown on the right indicates the battery voltage is below the undervoltage protection voltage, the controller has entered undervoltage
b) Retaining state, disconnect the load circuit. Using solar panels or charger to charge the battery when the accumulator
c) After the battery voltage reaches the undervoltage recovery voltage, the controller will restore power to the load, into normal working condition
1) Overload protection and processing methods：
The screen shown at right load circuit current is greater than the rated current or load short-circuit, overload state controller has entered. Reduce the load troubleshooting, press the button, restore power to the load
System fault | o r Fault has ruled out |
2) To charging failure handling method
a) Solar energy to battery charging, if there is no correct configuration solar panels of power or exceed rated charging current, voltage, will appear charge fault, the checking and debugging, press the button, recoverability work.k
Charge fault | Fault has ruled out |
3) Solar panels fault and processing:
a) 24 hours in the case of sun light, the controller is not charging, the solar energy is not connected or not connected correctly, check the solar panel to the connecting cable of the controller is open, troubleshooting, recoverability work.
No solar charge | Are charging |
