Find Sigineer Power In Construction Review (www.constructionreviewonline.com)

March 8th, 2017, Shenzhen, China Sigineer Power is recently interviewed by Construction Review (www.constructionreviewonline.com) which is Africa’s leading construction journal with printed copy readers of over 10,000 construction industry decision makers in both government and private sector dealing with housing, road, energy and water infrastructure. The readers consist of architects, engineers and contractors as well […]

Automatic Neutral-to-Ground Connection

All Sigineer Power’s inverters can be built with optional automatic neutral-to-ground switching. These inverters use an internal relay that automatically connects the AC neutral output to the vehicle/boat’s safety ground(“bonding” it) in Inverter Mode and disconnects it (“un-bonding” it) when they have connected to a qualified external AC source. This design avoids two neutral-to-ground connections from existing […]

Pros and cons and differences of a “low frequency” & “high frequency” inverter

Low frequency power inverters got the name of “low frequency” because they use high speed power transistors to invert the DC to AC, but drive transistors at the same frequency (60 Hz or 50Hz) as the AC sine wave output. High frequency power inverters typically drive the transistors at a high frequency closer to 50 […]

What is power inverter ? How does an inverter work ?

What is power inverter ? A power inverter is an electrical device that converts/changes direct current(DC) usually from batteries into alternating current (AC) to drive AC appliances such as electric lights, microwaves, power tools, TVs, kitchen appliances, radios, computers etc . The input DC voltage, output AC voltage and frequency, and overall power handling depend on […]

Find your must have power inverter for solar & hybrid systems

Since our outset, we’ve been kept being asked by customers about the ruggedness and toughness of Sigineer Power inverter chargers . And we’d like to elaborate why Sigineer power inverter is your must have power inverter for critical applications including solar & hybrid systems . Although there are other Chinese power inverters of similar boxes and seemingly close […]

Transfer Switch of Inverter Charger

While in the Standby Mode, the AC input of the inverter is continually monitored. Whenever AC power falls out of the trip voltages, the inverter automatically transfers back to the Invert Mode with minimum interruption to your appliances. The transfer from Standby mode to Inverter mode occurs in approximately 6 milliseconds, with the worst case […]

Rated Charging Amperage on Inverter Chargers

Sigineer Power’s inverter chargers are build with very strong battery chargers to recharge your batteries swiftly and safely. When you are using a generator to recharge the batteries, the charging capacity will go to peak in around 3 seconds, this may probably cause a generator to drop frequency, making inverter transfer to battery mode. It is […]

Inverter Soft Start and Overload Capacity

The Sigineer inverter chargers are designed with great overload capability and inverter soft start   Inverter Soft Start in Invert Mode The inverter is engineered with “Inverter Soft Start” feature. When the inverter is turned on, the output voltage gradually ramps up from 0VAC to rated voltage in about 1.2 sec. This effectively reduces otherwise […]
