This is how the solar meter displays when the water level and water temperature sensors are not connected, so focus on checking if the sensor signal line is disconnected (common).
Usually the uninterruptible power supply will beep and other prompts, usually there are equipment operation problems and battery problems, etc. If it is a system problem, the operation of the common bypass system, the uninterrupted power supply bypass power output of the system will bring intelligent prompts, which can be solved by operating the inverter. If it is a battery failure, the uninterruptible power supply will also output a message, and professionals are generally required to understand the operation of the battery. If it needs to be updated, the battery should be updated in time to avoidto affect use.
The most likely cause is an ultra high temperature alarm. Because the sun is strong in summer, the temperature practically reached 90° for several days in a row. There is no need to worry about this situation. . As long as there is water in the water tank, there is also an exhaust hole on the water tank. No problem if there is no blockage! If you are using electric heating, you must stop immediately!

Recommended: ""Dr Sun" Solar power (Class 1 energy efficiency, 3C certification), Sancang solar power (no need for water level sensor probes or 'solenoid valves), the utilization rates of heating and hot water are fast in rainy weather, and the after-sales rate is alsoent significantly reduced, saving both time and energy. Ordinary single storage solar heating only takes 20-30 minutes without sunlight, while single storage heating takes 2-3 hours!
