SmartGen | Genset Cloud Monitoring FAQ

SmartGen cloud monitoring modem can be connected to SmartGen cloud server (SmartGen Cloud Plus) via GPRS, network, WiFi to realize genset remote monitoring.

Cloud Monitoring Solution

A few days ago we found that some customers could use cloud monitoring normally when the unit was commissioned, but it did not work properly after it was sent to the site.The following common causes and solutions are specially sorted out for your reference!

─The controller communication address is changed by the customer on site, resulting in inconsistency with the unit communication address set in the background, making it impossible to communicate. The performance of fault is cloud modem RS485 light is always on, GPS and GPRS lights are flashing, power light is always on. This is a more frequent situation, be careful not to change controller communication address at will.

─Field controller 485 wire is unplugged, making communication impossible.

─GPS cannot position—the phenomena is that positioning has been the previous address, other data are normal, but cloud modem GPS light is always on. At this time, you can check whether there is a problem with GPS antenna connection.

─IOT cards are reused. Under the current rule, the IOT card can only match one cloud modem or integrated controller. If IOT card is activated for use in the first device and then inserted into another device for use, it will cause card locking to fail to communicate. In this case, you can put the card into the original device and wait for it to be unlocked or report to the IOT card vendor to re-bind the card with the new device. Remember that one card can only be used on one device in order to avoid locking. Do not use one card for multiple purposes!

─IOT card is normal but cloud modem cannot communicate. At this point may be the card is not correctly inserted, you can try to reinstall the card. Pay attention to whether the card slot is in good condition and can be closely combined with the card.

More questions continue to be collected and summarized. SmartGen, making control easier!

HGM9560+HGM9510 Methane Power Control in Jiangsu

Methane power generation is methane utilization technology that emerged with the continuous development of large methane tank construction and comprehensive utilization of methane. It applies methane produced by anaerobic fermentation treatment to the engine and is equipped with an integrated power generation unit to generate electricity and heat. The methane power is beneficial, energy-saving, safe and environmental, which is a cheap distributed energy.

This time the customer comes from a large dairy farm in Jiangsu, using methane to generate power. The site adopts two 250kW gensets using HGM9510 to parallel.


Power Control Site

The customer uses HGM9560 mains control mode at the same time, which can realize the distribution of genset and mains load power and unit load power via setting mains load percentage, thus realizing grid-connection without on-grid.

Set two HGM9510 as “Start on Demand” and “Balanced Running Time” to realize single unit running under low load mode and two gensets run in turn under long-time low power running mode.

HGM9510 is equipped with cloud monitoring module CMM366B-4G that can monitor genset data in real time and record power accumulation and accumulated running time via mobile APP and PC version “SmartGen Cloud Plus”.
