Check and maintain battery (group) and photovoltaic controller and inverter
Check and maintain batteries
(1) Keep the battery room clean to prevent dust from entering; Keep the room dry and well ventilated and well lit, but should not direct sunlight onto the battery.
(2) Indoor fireworks are strictly prohibited, especially when the battery is in charging state.
(3) When maintaining batteries, maintenance personnel should wear protective glasses, body protective equipment, and use insulation devices to prevent personnel from damaging batteries electric shock to prevent battery short circuit and circuit break.
(4) Often carry out the normal inspection of the battery.
(5) When using the battery normally, please do not use any organic solvent to clean the battery, and do not remove the battery for safety valve or in the battery to add any substance, battery discharge should be charged as soon as possible, so as not to affect the capacity of the battery.
Inspection and maintenance of pv controller and inverter
（1）The operation and use of photovoltaic controller and inverter should be carried out in strict accordance with the requirements and provisions of the operation manual. Check whether the input voltage is normal before starting; When operating, we should pay attention to whether the order of the switch is correct, and whether the indicator light and the head of the table are normal.
（2）Controller and inverter in the occurrence of open, over current, over voltage, overheating and other faults, generally will enter the automatic protection state and stop working. Once these equipment is down, do not turn on immediately, to find out the cause and repair the power again.
（3）When there is high pressure in the inverter chassis or cabinet, operators should not open the chassis or cabinet, and the cabinet door should be locked at ordinary times. When the ambient temperature exceeds 30 ° C, take cooling and heat dissipation measures to prevent device faults and prolong device service life. Check the temperature, sound and smell inside the machine regularly.
（4）Maintenance and overhaul of controllers and inverters: Strictly check whether the cables of controllers and inverters are loose (such as fuses, fans, power modules, input and output terminals, and grounding), and immediately repair the loose cables.
