6 Maintenance

This chapter describes the maintenance of the MEH048-401BX HEMS system, including the surge arresters maintenance, routine maintenance and monthly maintenance.

6.1 Surge Arresters Maintenance

& Notes：

Before rainy season and after lightning storm, carefully check the lightning arrester to ensure that it is in perfect conditions. If the lightning arrester is damaged, replace it in time.

All the arresters are monitoring by MONITOR. Once any lightning arrester is damaged, the MONITOR will generate visual and audible alarms to alert maintenance personnel for timely replacement. The lightning arrester is hot pluggable, that is, it can be directly replaced without cutting off the power supply.

6.2 System Maintenance

To ensure a reliable power supply system, the user should perform routine maintenance properly. The maintenance items are described as below:

l Periodically clean the equipment to keep any dust away.

l Weekly check the parameters of the system. If there is any abnormity or alarm, handle it promptly.

l Check the lightning arrester monthly and after a lightning storm. If any is damaged, replace it promptly.

l Monthly check the input and output cables. Check whether the cables are reliably and properly connected. Replace any damaged cable in time.

l Check each air switch for its flexibility and for any possible burn once every half a year.

l Maintain the batteries according to the appropriate documents.


6.3 Storage Requirement

The following precautions shall be taken during the equipment storage:

l Storage temperature: -40°C ~ +70°C.

l Keep the original package and place the equipment in the direction marked on the package.

l The equipment should be stored in dry warehouses and be kept from exposure to sunshine or rainwater.



7 Alarming and Handling

This chapter describes the alarms of the MEH048-401BX HEMS system, and how to handing there alarms.

7.1 Alarming Introduction

In case of the system fault, the monitor unit will generate alarm by audible, visible alarm and text messages. When alarming, the red ALM indicator on the monitor unit glows, and the buzzer rings. If the fault is severe, the monitor unit will report the alarm to the remote monitor center at once. If the fault is not severe, the monitor unit does not report the alarm until polled by the monitor center.

The Rectifier, Solar module and the monitor unit, are designed with reliable internal protection, so the failure of a single module does not affect the operation of the whole system. When a module fails, it automatically exits from service. When the monitor unit fails, the battery keeps working in the float charging mode, so the system still works normally.

& Notes：

l The system can still work normally when disconnected with the monitor unit. When disconnected with the monitor unit, the system fault data cannot be transferred to the remote monitoring center, and fault message is not displayed locally.

l There are three alarm levels, which can be set through the background monitor software.

7.2 Handing

In case of any system alarm, the maintenance personnel should immediately check corresponding device according to the monitor unit, specify the fault type and take corresponding measures. Only professional personnel are allowed to dismantle the equipment.

Some alarms will affect the system output, while others will not.


Table 7.1 Alarms affecting system output and the solutions

Symptom Solution The battery voltage is too low

l Make sure that other standby power supply is available so that the system will provide power continuously in case of AC source failure.

l Disconnect the two battery input fuse to protect the battery and prevent the battery from over-discharge.

Load over-/under-voltage occurs

l Check the output voltage of each module and the operation status of the loading equipment.

l Check whether the monitor unit is damaged Battery loop remains opened

Check whether the battery fuse is damaged, whether the monitor unit is damaged, and whether the data collected by the monitor unit is normal

Module(Rectifier, solar, Wind) is abnormal or damaged

Replace the faulty module with a standby one and repair it

Table 7.2 Alarms not affecting system output and the solutions

Symptom Solution AC input over-/under-voltage

Cut off the AC input power and use the battery to supply power until the AC input voltage recovers.

Rectifier output current limiting occurs

l Check whether the load gets faulty. l Check if the system is in the charging status, and

measure the output current of the rectifier. l Check the rectifiers for any possible fault. If any

rectifier is faulty, replace it. The monitor unit is abnormal

Restart the monitor unit to reset it. If the problem persists, take out the monitor unit and repair it.

LCD display disorder Restart the monitor unit to reset it. If the problem persists, take out the monitor unit and repair it.

Invalid keyboard operations

The CPU is processing other processes. Wait for a while.

Monitor unit has no power

Check if the input switch of the monitor unit is closed, and if the monitor unit is properly inserted.

& Notes：

To prevent any special case from affecting the normal operation of the system, the user shall learn about the handling procedures.
