eMPPT30 Solar Charger controller

Features:

The product adopts DC/DC converting technology and MCU technology. It can adjust the working point of the solar panels array intelligently to make the solar panels array realize the maximum power output. When the external condition changes, eMPPT controller bases on the MCU theory to track the maximum working point of the solar panels, this can improve the using efficiency of the solar panels and decrease the solar generating cost. Compared with average solar charge controllers, eMPPT can improve the output efficiency of the solar panels by 5% to 30 %( the output increasing proportion affected by the factors such as the attribute of the solar panels, environmental temperature and lighting conditions). The product adopts in big screen lattice LCD, and uses the vivid icons to indicate the parameters. It has concise and vivid interface. The product is wall mounting installation. Please refer to chapter 2.1 for the installing dimensions.

Product functions

	Functions	instruction
1	maximum power point tracking	Adopting DC/DC converting technology and MCU technology to realize the maximum output of the solar panels
2	battery reversed connection protection	Battery polarity connecting to the controller reversely (under the condition not connecting solar panels) will not cause damage to controller. It can work normally after connecting right.
3	Anti-battery reverse discharge	When solar panels voltage is less than battery voltage, the battery will not charge to the solar panels array.
4	Anti-solar panels reverse connection	Solar panels array polarity connecting to the controller reversely will not cause damage to controller. It can work normally after connecting right
5	three-stage charge control	Bulk Absorption Float
6	float charging voltage adjustable	The users can adjust the float charging voltage within a certain scope.
7	temperature compensation for float charging voltage	Referring to the current battery temperature, take 25℃ as a benchmark, the controller will compensate the float charging voltage by -4mV/Cell/℃. For 12V battery, compensation voltage U=(t-25)6(-0.004)V；For 24V battery, compensation voltage U=(t-25)12(-0.004)V；For 48V battery, compensation voltage U=(t-25)24(-0.004)V
8	Elevating charging voltage adjustable	The users can adjust the elevating charging voltage within a certain scope
9	solar panel input deviated from maximum power point	When solar panel input power is over the acceptable power for the controller, the controller will make the solar panel work deviated from the maximum power to prevent itself damaged. So the controller charges the battery by rated current.
10	internal overheating protection	When the internal temperature sensor detects excessive temperature, the controller will stop working to prevent it being damaged. It will resume working again when the internal temperature drops to a certain degree.
11	temperature controlling fan	When the internal temperature sensor detects the temperature exceeding a certain degree, the controller will start the cooling fan until the temperature drops to a certain degree.
12	panel over voltage protection	When the input voltage of the solar panels exceeds the rated voltage, the controller will start protection automatically and stop working until the input voltage resumes back to the normal scope.
13	remote controlling function	This optional function can make it possible to view and set the parameters of the system on PC.

Installing dimension

We suggest installing the controller on the vertical wall, and ensure there is the space over 10cm around the controller for heat emission.

1. We suggest the user to use the sheathed cable with the cross-sectional area over 6mm2.
2. We suggest installing breaker and fuse on the negative loop of battery and solar panels.
3. Set the controller’s ground terminal to reliably connect to the system ground bus.
4. The capacity of the controller internal over voltage absorption is limited. Please make sure connect the solar panel to the controller after connecting to the mine exchange line box.

Wire & tool preparation
⑴Prepare 6 mm2 black and red sheathed cables, each one roll. Prepare several copper noses ofФ6-6mm2 since controller adopts inФ6 terminals
⑵Hydraulic pliers(for crimping copper nose and cable) and 6 mm2 die, one couple, 10mm wrench, 2 sets, Phillips screwdriver, 1 set, cutting pliers, 1set
⑶Cut the cables according to the cabling requirement. Use hydraulic and die to connect the copper nose and cables tightly, and prepare all the cables well.

Installing process
⑴If breaker is installed in the battery loop, please make the breaker open. If fuse is installed, please take out the fuse to prevent the phenomena of contact ignition.
⑵Use the prepared cables to connect the +,- polarity of battery to the battery terminals on the controller. Please make sure the connecting of the polarity is correct.
⑶Use the prepared cables to connect the solar panel output of the main convergence box to the solar panes terminals on the controller. Please make sure the connecting of the polarity is correct.
⑷Use the prepared cables to connect the ground terminals to the ground box of the system.
⑸ Insert the temperature sensor to the right place on the controller.
⑹Close the breaker of the battery loop or insert the fuse of the battery loop, if the controller LCD screen starts to show the signal, the controller will start to work. And if the LCD has no signal, please check whether the connecting of the polarity is correct, whether the connecting cables is in good condition, whether the breaker is closed, whether the fuse is inserter. Wait until the LCD has signal, and then go to next step.
⑺Close the breaker of the solar panels loop or insert the fuse of the solar panels loop, then the controller LCD screen will show the solar panels voltage. If the LCD shows the voltage is 0V, please check whether the breaker in the solar panels loop is closed.
