Product Detail

Product Overview:

Featuring a 51.2V standard voltage platform, this LFP all-in-one energy storage battery integrates a high-efficiency inverter (conversion efficiency ≥96%) and intelligent controller, directly connecting to 10-20kWp solar systems for real-time solar energy conversion and storage. It supports bidirectional charging/discharging, enabling energy storage during grid off-peak hours to reduce electricity costs while serving as an emergency power source during outages. The integrated design saves 30% installation space, and with an intelligent temperature control system and BMS battery management system, it ensures safe operation in environments from -15°C to +50°C, offering over 3,000 cycles (80% DOD). Ideal for home energy storage, solar self-consumption, peak-valley pricing management, and off-grid backup power, it simplifies energy system configuration while enhancing power reliability.

Key Features:

  • Integrated photovoltaic inverter, energy storage battery, and energy management system.

  • Built-in MPPT inverter-controller all-in-one unit with PV interface for direct PV charging.

  • Equipped with Grade A brand lithium iron phosphate (LFP) cells, ensuring safety, reliability, and long cycle life.

  • Features dual AC sockets for powering household appliances.

  • Advanced BMS (Battery Management System) with multiple safety protection functions.

  • Protection against overcharge, overcurrent, short circuit, overload, overheating, and error code display.

  • Maximum discharge current up to 100A.

  • Comprehensive protection for unattended operation.

  • Built-in LCD screen and communication interfaces (CAN or RS485) to display real-time battery status.

Ratio Trial Verification Method for Current Transformers
Ratio Trial Verification Method for Current Transformers
Fellow electric power calibration workers, you must have encountered this situation: The nameplate of an outdoor current transformer has been tormented by wind, sun, rain, and freezing, to the point where the transformation ratio is indistinguishable! Don't panic, we have a solution - use a current transformer calibrator and through the “transformation ratio trial calibration method”, we can figure out the actual transformation ratio and errors clearly. Here, taking the SHGQ - DC typ

I'm Felix, a 15-Year Veteran in the CT Industry, Sharing What You Need to Watch Out ForHi everyone, I'm Felix, and I've been working with current transformers (CTs) for over 15 years. Today, let’s talk about why the secondary insulation of outdoor CTs sometimes drops, and what you can do to prevent it.Common Causes:1. Moisture Ingress — Poor Sealing is the Biggest Problem!Outdoor CTs are constantly exposed to wind and rain. If the sealing isn't tight enough, moisture can get inside a

What are the troubleshooting methods for current transformers?
What are the troubleshooting methods for current transformers?
As a front - line fault maintenance worker, I deal with current transformers (CTs) daily. A CT’s secondary winding in operation must never open - circuit! Once open - circuited, the secondary current and demagnetizing potential vanish. All primary - side magnetic potential then becomes the iron core’s exciting potential, sharply increasing its magnetic flux density. High voltage on the secondary side will endanger safety anytime.Despite strict power operation regulations, user electr
