ALP220-EF Protection for a Factory PV Cabinet in Selangor
Project background A factory shutdown gives a panel builder a limited window to connect a new PV cabinet. This Selangor application proposal focuses on preparing the protection circuit before that window arrives. ALP220-EF is assigned to the specified current-protection duty on one feeder, wi...Read more -
A HaLow Communication Proposal for Factory Rooftop PV in Shah Alam
Project background A factory adding rooftop PV may have room for the inverter upstairs but no convenient communication route to the meter downstairs. This proposal considers an occupied Shah Alam factory where the approved PV design requires export limitation. The installation needs a dependab...Read more -
A Practical Maximum-Demand Monitoring Architecture for Malaysian Facilities
At 2:30 pm, production is running, the cooling load is rising and a second compressor starts. Which loads stay high together long enough to set the factory’s demand peak? A practical monitoring layout Monitor the main incomer with APM521, then add meters on selected branches. For a wired ins...Read more -
Preparing for EECA Reporting? Start with Better Energy Data
Your electricity bill shows how much energy the site used. But if consumption rises, can you tell whether it came from cooling, production or equipment left running after hours? For Malaysian facilities preparing energy records under EECA 2024, that breakdown helps explain the numbers. A practic...Read more -
Which Protection Does Your PV Cabinet Need? Acrel ALP220-EF
When selecting protection for a PV grid-connection cabinet, which functions does the project actually need? Starting with a long list of general feeder protection functions can make that decision harder. The single-line diagram is a better starting point. What protection is already provided by t...Read more -
From Energy Data to EE&C Reporting Support with Acrel IoT EMS
You have all the electricity bills. Why is there still missing data when it is time to prepare an EE&C report? For many factories and commercial buildings, the monthly total is easy to find. The harder questions come next. How much went to cooling and how much to production? Why was th...Read more -

Why a 30-minute peak matters For TNB customers billed with Maximum Demand, the monthly value is based on the ...Read more -
Solar PV Installed, but Power Factor Dropped? Here’s How to Fix It
The PV system is doing its job. Daytime grid consumption is down and the inverter output looks normal. Then someone checks the main incomer and finds that the power factor is worse than it was before the solar installation. That result can look contradictory, but it is not unusual at ...Read more -
Power Factor Dropped to 0.3 After Grid-Connected PV? How ANSVG Turned Penalties into Credits？
The factory installed solar PV to cut energy costs, but its power factor fell below 0.5 after grid connection. Power-factor adjustment charges appeared every month, and 13 of 40 capacitor units bulged and failed. After Acrel ANSVG static var generators were installed...Read more
