A pure sine wave inverter converts DC (Direct Current) power from batteries into AC (Alternating Current) power that precisely mimics utility-supplied electricity. Unlike modified sine wave inverters, pure sine wave inverters produce clean, smooth power essential for sensitive electronics, medical equipment, and modern appliances. WZRELB’s pure sine wave inverters maintain a consistent wave pattern that prevents interference, noise, and potential damage to your devices.

To determine the right size, you’ll need to calculate the total wattage of all devices you plan to run simultaneously. First, add up the running watts of each device and consider surge watts for motors and compressors. For safety and optimal performance, we recommend choosing an inverter with 20% more capacity than your calculated needs. For example, if your total power requirement is 1000W, you should opt for a 1200W inverter to ensure stable performance and longevity.

Yes, WZRELB pure sine wave inverters are fully compatible with solar power systems. However, you cannot connect the inverter directly to solar panels. The proper setup requires connecting solar panels to a charge controller, which then connects to a battery bank, and finally to the inverter. This configuration ensures stable power flow and protects both the inverter and your connected devices from power fluctuations typical of direct solar input.

Runtime depends on three main factors: your battery capacity (Ah), inverter power draw, and connected load. As a practical example, a 100Ah 12V battery powering a 1000W inverter with a 500W load will run approximately 2 hours, accounting for efficiency losses and recommended 50% battery discharge depth. To calculate your specific runtime, use this formula: Battery Amp Hours multiplied by Battery Voltage multiplied by 0.85 (efficiency factor), divided by your Load Watts equals runtime in hours.

Installation is generally straightforward but requires careful attention to safety protocols. The process involves mounting the inverter in a well-ventilated area, connecting it to batteries using appropriately sized cables, ensuring correct polarity, installing proper fusing, and establishing good grounding. We provide comprehensive installation manuals with every unit, though we recommend professional installation for larger systems to ensure safety and optimal performance.

Our comprehensive warranty package includes a 12-month manufacturer warranty against defects, a 30-day money-back guarantee, and free technical support throughout the product’s lifetime. We maintain a stock of replacement parts to ensure quick resolution of any issues. To activate your warranty, simply register your product within 30 days of purchase, and keep your proof of purchase for any future warranty claims.

WZRELB pure sine wave inverters are specifically engineered to protect your electronics through multiple safeguards. Our inverters incorporate overload protection, short circuit protection, over-temperature protection, and low/high voltage protection. The pure sine wave output maintains less than 3% Total Harmonic Distortion (THD), ensuring safe, clean power delivery for even the most sensitive electronic devices.

Pure sine wave inverters provide superior performance across all metrics that matter. They’re compatible with all AC electronics, operate more quietly, generate less heat, and offer better efficiency. While the initial investment is higher than modified sine alternatives, they provide better long-term value by extending equipment life, eliminating interference with displays and audio equipment, and ensuring compatibility with sensitive electronics and medical devices.

Proper maintenance is straightforward and essential for optimal performance. We recommend monthly inspection of all connections, regular cleaning of ventilation areas, checking for any signs of corrosion, verifying mounting security, and testing protection systems. Keep the operating environment dry and cool. Following these simple maintenance steps will significantly extend your inverter’s life and ensure consistent performance.
