Load selection: (1) The total power of the load should not exceed the output power of the solar panel or controller. (2) The load power should be selected according to the capacity of the battery. The basic requirement is that in normal sunshine, the solar energy that can be stored by the battery every day can meet the power consumption of the load for one day or have a surplus. (3) For the AC load, select an appliance that can use the output waveform characteristics of the inverter. If an appliance that can only use a sine wave is used, an inverter with a sine wave output should be selected. When installing and using a new home solar photovoltaic system, the following must be observed: (1) Strictly avoid short circuit of various household appliances and wires, and the installation of solar panel brackets must be firm and stable; (2) The solar panels must be installed in the correct azimuth and tilt angle to avoid dust pollution and the cabinets avoid water soaking; (3) When the voltage is indicated in the alert zone below 11V (red zone or hear the alarm sound), indicating that the battery is not fully charged, the switch should be turned off immediately, stop using it, and recharge it to the normal use area (or green zone). Use (except products with automatic control function); (4) Solar panels or controllers and inverters should not be frequently plugged after they are connected; (5) The cabinet must not be inclined, and it must not be turned upside down to prevent the electrolyte from overflowing, damaging the equipment or injuring the human body; (6) The two poles of the battery must not be short-circuited, otherwise the battery will be damaged; (7) Lamps must be equipped with special high-efficiency energy-saving lamps. Do not use other lamps. Don't touch the lamp electrodes. Do not extend the wires or other electrical wires without authorization. It is better to use the battery fully before use. ; (8) It is forbidden to connect the DC power supply and the electrical appliance to the AC power supply; (9) Minors under the age of 16 must not touch or remove. flat lifting sling,polyester flat webbing sling,flat lifting sling price Jiangsu Zhongyi Work Rigging Co., Ltd. , https://www.zy-rigging.com
