Detailed Comparison
1. Power & Solar Handling (The Core Performance)
This is the most significant difference between the two models.
- KNOX KRYPTON 11.5KW: The KNOX unit is demonstrably more powerful on paper. It offers a slightly higher continuous output of 11.5kW compared to Ziewnic’s 11kW. More importantly, it boasts a massive Maximum PV Input of 15,000W. This “oversizing” capability is a huge advantage, allowing you to connect a larger solar array to maximize energy generation, especially during overcast days and the winter months. Its dual MPPTs can also handle a higher current (30A each), making it more compatible with the latest high-wattage solar panels.
- ZIEWNIC ULTRA 11KW: The Ziewnic inverter has a still-impressive 11kW output and a Max PV Input of 12,000W. While lower than the Knox, this is still ample for most large residential or small commercial setups. Its dual 27A MPPTs are sufficient for the majority of solar panels currently on the market.
Verdict: For those looking to maximize their solar generation potential and future-proof their system for even more powerful panels, the KNOX KRYPTON has a clear edge in raw power handling.
2. Key Features & Usability
Both inverters are packed with modern features expected in a premium hybrid model.
- KNOX KRYPTON 11.5KW: The user interface is a standout feature, featuring a large HMI touchscreen which is generally more intuitive and easier to navigate for settings and monitoring. A unique and highly practical feature is the built-in DC output, allowing you to directly power DC appliances like fans, routers, and LED bulbs without conversion losses.1 It also includes a replaceable fan and an anti-dust kit, which are thoughtful additions for longevity in the Pakistani environment.
- ZIEWNIC ULTRA 11KW: Ziewnic emphasizes durability and speed. It features a conformal coating on its circuit boards, which provides superior protection against dust and humidity—a significant advantage in many parts of Pakistan. It also boasts a zero transfer time, ensuring a completely seamless switch to battery power during an outage, which is ideal for sensitive electronics. It offers optional support for advanced safety features like AFCI (Arc Fault Circuit Interrupter).
Verdict: This is a tie, depending on user priorities. If a modern, user-friendly interface and direct DC power are more appealing, KNOX wins. If maximum internal protection against the elements and instantaneous transfer time are critical, ZIEWNIC is the better choice.
3. Price and Value
- KNOX KRYPTON 11.5KW: Positioned as a premium, high-performance model, its price (around PKR 385,000) reflects its superior power handling capabilities.
- ZIEWNIC ULTRA 11KW: This model offers a highly competitive price point (around PKR 305,000 – 315,000), making it an excellent value proposition for those who can work within its 12,000W PV limit.
Verdict: For budget-conscious buyers, the ZIEWNIC ULTRA offers incredible value, providing a powerful 11kW hybrid solution for a significantly lower investment.
Conclusion: Which One Should You Buy?
Your choice between these two excellent inverters comes down to your specific needs and budget.
Choose the KNOX KRYPTON 11.5KW if:
- You want to install the largest possible solar array (over 12,000W) to maximize generation.
- You plan to use the latest, high-current solar panels.
- A large, modern touchscreen interface is important to you.
- The idea of a built-in DC output for running small appliances is appealing.
Choose the ZIEWNIC ULTRA 11KW if:
- You are looking for the best possible value and a lower upfront cost.
- Your planned solar array is 12,000W or less.
- Your inverter will be installed in an area with high humidity or dust, where the conformal coating offers extra peace of mind.
- You run highly sensitive equipment that would benefit from zero transfer time during outages.
Both KNOX and ZIEWNIC have established a strong presence in the Pakistani market, offering competitive products with modern features. Your final decision should align with your system’s design, your budget, and the features you value most. For more reviews and local market insights, consider visiting platforms like top5pk.com.
