First choice for DIY off-grid solar system
First choice for DIY off-grid solar system

The first batch of Hestia series off-grid solar system has been produced and deliverd to users. Our customers are looking forward to Hestia. The Hestia performed very well in the 3 months of internal testing, especially the build-in Grand A LiFePO4 battery. After 4000 cycles of repeated testing, DOD>80%, which greatly improves the stability of... » read more

BP & BPlus Series pure sine wave inverter Compare
BP & BPlus Series pure sine wave inverter Compare

The BP series pure sine wave inverter is one of our earliest and most popular inverter. So far, we have made some technical updates to it, and in 2019 we have officially launched an upgraded BPlus series pure sine wave inverter for the BP series pure sine wave inverter. The BPlus series pure sine wave inverter  is not just a... » read more

Inverter PCB ultrasonic cleaning from CNBOU

BP series pure sine wave inverters support 12VDC from 300W-6000W. We all know that if 6000W inverter connected with 12V battery, its current could up to 600Amp. Inverter’s PCB board cannot undertake such high current whatever type PCB board you used. So engineers will add copper wires under PCB board to enhance its current carrying capacity.... » read more

Protection System of BPlus series inverter
Protection System of BPlus series inverter

We designed extremely sound and intelligent protection functions for BPlus series pure sine wave inverter. BPlus inverter has red and blue indicator lights to show three different protection states. If the inverter is over-load, its red light will flicker; if the inverter is under-voltage, its blue light will flicker; if the inverter is short-circuit, over-temperature or... » read more

Testing 5000W inverter under minus 40°C for 15 hours
Testing 5000W inverter under minus 40°C for 15 hours

The BP series pure sine wave inverter 5000W data-sheet shows running Temp is -10°C to 50°C. Our customer let us test the BP inverter running in -10°C for 8 hours, but we tested for 15 hours under -40°C.  Live up to expectations, the inverter works fine. This means that when the inverter is in a cold environment below zero, such as... » read more

Best battery type for off grid solar inverter
Best battery type for off grid solar inverter

Today we show the HeliosII-485MCP off grid solar inverter battery charge strategy. We know many inverters are flaunted to support all types of battery, such as: AGM, GEL, LifePO4 etc. But for battery charge strategy, It is not clearly defined. Over/low voltage value, what time from float charge (FC) to constant current (CC), when constant current (CC) to constant... » read more
