1. Important Safety Instructions Please keep this manual for future investigations. This manual contains all the security, installation and operating instructions of Muse photovoltaic controller. The following icons indicate a specific action for potentially hazardous situation or important safety steps throughout the entire manual instructions. WARNING: Indicates a potential danger, when performing this task should be more careful. Alert: Indicates a key program of controller safe and correct operation.
technique, represents the latest state of the art photovoltaic, which has many excellent performance: Excellent thermal design and natural air cooling. Innovative MPPT technology, can significantly improve the energy efficiency of solar systems, and the conversion efficiency could be up to 97%. Having broad applicability, automatically identify day / night. Fast scan the entire IV curve and track the maximum power point of the photovoltaic cells.
In addition, there is a dedicated controller on Muse RS485 communication interface used to implement communication with other monitoring equipment, the theoretical maximum communication distance of 1000 meters (requires external power supply). Although Muse controller is easy to operate and use, in order to allow you to make better use of all the functions of the controller, and improve your PV system, we recommend you to spend a little time understanding the instructions in this manual and instructions.

2.2 Optional Parts Remote display unit (Model: MX-2) Remote display unit can display a lot of information systems work, fault information. Information display on the backlit LCD, while buttons and the digital display will be very easy to operate and read. The display unit can be easily installed in or on the frame on the wall, MX-2 comes standard with a 2 m connection cable (can also be customized according to user needs), a mounting frame box. MX-2 connected via RS485 interface.
Battery Terminal Blocks on the controller can either just the same battery connection, you can connect the same set of batteries. Subsequent manual instructions are for single use only batteries, but the same applies to a group of battery systems. Cable system according to no more than 3A / mm2 to select a current density. 3.
damage the controller wiring if not follow this order. Note: Muse is a total negative Control. Alert: Do not exceed the load-side connection of electrical equipment controller surge power, to prevent damage to the controller! Alert: When you need to move to use, make sure all connections are secure. Due to a series of virtual contact may cause heat buildup, and in severe fire.
insurance wiring, make sure the wiring is correct before turning insurance. Step 2: Connect the load Muse controller can be connected to the load side of the rated working voltage with the same battery rated voltage DC electrical equipment, the controller power up to the load with the battery voltage. Figure 3-2 DC load connection According to Figure 3-2 connect the positive and negative load to the load terminal blocks of the controller.
WARNING: RISK OF ELECTRIC SHOCK! PV module may generate a high voltage, be careful to prevent electric shock when wiring. Muse controller can apply 12V, 24V off-grid solar modules, can also use the open circuit voltage does not exceed the specified maximum input voltage and network components. System solar module system voltage is not lower than the voltage. Figure 3-3 PV panel connection Step 4: Optional parts If necessary, install a remote display unit or a communication module (sold separately).
solar array. The tracking algorithm is fully automatic and does not require user adjustment. Muse controller will track the array maximum power point voltage (Vmp) as it varies with weather conditions, ensuring that maximum power is harvested from the array through the course of the day. Current Boost In many cases, MPPT technology will ‘boost” the solar charge current. For example, a system may have 8 Amps of solar current flowing into the Muse and 10 Amps of charge current flowing out to the battery.
off-grid module. 12V Solar battery current and voltage 12VSolar battery output power Figure 4-1 Nominal 12V solar module I-V curve and output power graph. The array Vmp is the voltage where the product of current and voltage (Amps × Volts) is greatest, which falls on the ‘knee‘ of the solar module I-V curve as shown in Figure 4-1. Because Traditional controllers do not operate at the Vmp of the solar modules(s), energy is wasted that could otherwise be used to charge the battery and power system loads.
Bulk Charge In this stage, the battery voltage has not reached boost voltage yet and 100% of available solar power is used to recharge the battery. Boost Charge When the battery has recharged to the Boost voltage set point, constant-voltage regulation is used to prevent heating and excessive battery gassing. The Boost stage remains for some time and then goes to Float Charge.
the minimum threshold, PV status indicator is lit, indicating that PV input circuit is normal, the controller starts scanning. Charger Indicator: Charger indicator flashed, the controller is in bulk charging state; Charging indicator light, the controller enters floating state. Battery Over-voltage Or Battery Lost: Charging light goes out, the fault indicator flashes and the display shows ‘BT-LO’ fault code. See chapter 5 deal with failure.
turns off while display ’BL-OC’ fault code, see chapter 5 deal with failure. DC Load-side Overload Indicator: When the DC load-side output than the rated current, but did not reach 150%,the controller automatically adjusted according to the current value of allowing current overload time, exceed the allowable time, the controller off the DC output, fault indicator flashes while display ‘RL-OL’ fault code, see chapter 5 deal with failure.
for the machine due to overheating, the controller will pause charging waiting the temperature dropped, then the fault indicator flashes the charge indicator turns off while display ’Ar-OH’ fault code, see chapter 5 deal with failure. 4.

such as turn-on delay setting value of’00.01’,ie one minute delay after the DC load-side open. 1 Manual Model This is manually control the DC load terminal opened and closed by pressing “∧”to perform the switching operation, when pure manual mode, light control and time control mode is disabled.
PV input voltage is too low, failing to scan allows the controller to start charging, check the reliability of the photovoltaic panels with the controller connected PV open circuit voltage is less than the system voltage, PV panels of light is good, without having to manually reset the fault and troubleshooting controller starts scanning automatically after charging.
Note: When the battery side hard short-circuit faults exist, it is possible to burn batteries or even cause a fire, it is recommended that controllers and connected via an external insurance. Load short circuit When the load short circuit, the controller is automatically protected, troubleshooting cannot be reset, protection must by pressing the "ESC" key to remove.
lightning area, it is recommended to install an external arrester. Note ： No led LCD display, test battery with a multi-meter the voltage across, at least 9V to launch controller! 5.2 Maintenance of power systems In order to maintain optimal performance for long time, we recommend the following checks twice a year. Confirm that the controller is securely installed in a clean, dry environment.
6． Warranty promise Muse Controller with 2 years warranty and warranty starting from the date of sale. Maintenance procedure Before calling maintenance, control user manual to determine the controller has a problem. If not resolved, take the controller send it back to the company in question, freight prepaid, and provides information about date and place of purchase.
Maximum input voltage is the open circuit voltage applications at the lowest temperature conditions of PV modules (VOC), that is, the value of VOC at this time should be less than or equal to the maximum input voltage of PV terminal specified in the text.
