300W Pure Sine Wave Inverter
The SureSine 300 Watt Pure Sine Wave Inverter from Morningstar Corp. is the perfect solution for those seeking reliable, high-quality power for a variety of applications. This inverter provides 300 watts of continuous power, making it ideal for powering a wide range of devices and appliances in off-grid situations.
The SureSine inverter is designed to convert DC power from your solar panels or battery storage into AC power, which is used by most household appliances. What sets this inverter apart is its pure sine wave output, which is the same type of power supplied by the grid. This ensures your devices run smoothly and efficiently, without the risk of damage caused by inferior quality power.
Not only does the SureSine inverter provide reliable power, but it also comes packed with features for ease of use and longevity. It has a robust design to withstand extreme environments and mission-critical applications, making it a trusted choice in over 100 countries.
Whether you’re powering lighting in agricultural settings, providing power for residential use, or ensuring continuous operation of telecom systems, the SureSine 300 Watt Pure Sine Wave Inverter is a reliable choice. It’s also perfect for use in rural electrification projects, RVs, caravans, marine applications, and security and surveillance systems.
With the SureSine 300 Watt Pure Sine Wave Inverter, you can have peace of mind knowing you have a reliable power source wherever you need it. So why wait? Invest in reliable power today.
The new 300 Watt SureSines greatly expand our inverter offering that started with the acclaimed SureSine Classic. The new SureSine line has:
- Wireless Android and iOS utility apps for set-up and monitoring with remote devices, plus Bluetooth communications
- Multiple AC hardwire remote terminal options on selected models
- Industry leading safety, low-noise and high performance NRTL certifications for reliability and system conformance
The SureSine line uses industrial-grade build quality throughout, with models built around premium toroidal transformers for improved sinewave stability. Designed for the most demanding off-grid mission-critical installations, they feature:
- Superior thermal performance with fanless design means higher reliability– for example, the 300W model doesn’t derate until 45 C and delivers 200W at 60 C. That’s outstanding performance in its power class.
- Full communications capabilities include: RS485, USB, Ethernet, MS-CAN, Bluetooth while using industry-standard MODBUS protocol.
AC options include: hard-wire terminals for all markets and power levels, Type B for North America 150, 300, and 700W versions, and Universal for International 150, 300, and 700W versions.
Wireless Android and iOS mobile apps included for set-up and monitoring with remote devices.
