5. It's recommended that a fuse or breaker be installed outside the controller. 6. Before installing and wiring the controller, make sure to disconnect the photovoltaic array and the fuse or breaker close to the battery terminals. 7. After installation, check if all connections are solid and reliable so as to avoid loose connections that may give rise to dangers caused by heat accumulation. -

protection functions built inside the controller, component damage caused by installation errors or system failures can be avoided to the greatest extent possible. 1.2 Product Features With the advanced dual-peak or multi-peak tracking technology, when the solar panel ◆ is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum power point. - Page 6 The controller is equipped with an LCD screen with which users can not only check ◆ device operating data and statuses, but also modify controller parameters. The controller supports standard Modbus protocol, fulfilling the communication needs ◆ of various occasions. The controller employs a built-in over-temperature protection mechanism.

Page 8: Introduction To Maximum Power Point Tracking Technology
○ Solar panel "-" interface 1.4 Introduction to Maximum Power Point Tracking Technology Maximum Power Point Tracking (MPPT) is an advanced charging technology that enables the solar panel to output more power by adjusting the electric module's operating status. Due to the nonlinearity of solar arrays, there exists a maximum energy output point (maximum power point) on their curves. - Page 9 Fig. 1-2 Solar panel output characteristic curve Meanwhile, due to changing ambient temperature and illumination conditions, the max. power point varies frequently, and our MPPT controller can adjust parameter settings according to the environmental conditions in real time, so as to always keep the system close to the max.

- Page 12 By default, boost charging generally lasts for 2h, but users can adjust preset values of duration and boost voltage point according to the actual needs. When the duration reaches the set value, the system will then switch to floating charging. Equalizing charging Warning: risk of explosion! In equalizing charging, an open lead-acid battery can produce explosive gas, therefore the...

Nor shall the controller be installed in an enclosed space where battery gas may accumulate. Warning: danger of high voltage! Photovoltaic arrays may produce a very high open-circuit voltage. - Page 16 Hot air Cold air Fig. 2.1 Installation and heat dissipation Step 1: choose the installation site Do not install the controller at a place that is subject to direct sunlight, high temperature or water intrusion, and make sure the ambient environment is well ventilated.
- Page 17 Step 4: wire First remove the two screws on the controller, and then begin wiring operation. In order to guarantee installation safety, we recommend the following wiring order; however, you can choose not to follow this order and no damage will be incurred to the controller.

Warning: when the controller is in normal charging state, disconnecting the battery will have some negative effect on the DC loads, and in extreme cases, the loads may get damaged. Warning: within 10 minutes after the controllers stops charging, if the battery's poles are reversely connected, internal components of the controller may get damaged. - Page 20 Steady on, charging in max. power 常亮，最大功率充电 慢闪，提升充电 Slow flashing, boost charging 单闪，浮充充电 Single flashing, floating charging 快闪，均衡充电 Quick flashing, equalizing charging 双闪，限流充电 Double flashing, current-limited charging Indicator state Charging state ○ Steady on MPPT charging ○ Slow flashing Boost (a cycle of 2s with on and off each charging lasting for 1s)

Note: after system voltage setting, power supply has to be switch off and then on again, otherwise the system may work under an abnormal system voltage. The controller enables users to customize the parameters according to the actual conditions, but parameter setting must be done under the guidance of a professional person, or else faulty parameter settings may render the system not able to function normally. - Page 27 Battery reverse connection protection If the battery is reversely connected, the system will simply not operate so as to protect the controller from being burned. Photovoltaic input side too high voltage protection If the voltage on the photovoltaic array input side is too high, the controller will automatically cut off photovoltaic input.
