Frequently Asked Questions about our On-grid Inverters.
Selecting the right capacity (kW) is crucial. While a general best practice is to match the inverter's AC output to the PV array's size, modern regulations often allow for significant DC 과대 설계. This strategy (e.g., installing 13kWp of panels on a 10kW inverter) maximizes energy harvest in real-world conditions. We can help you determine the optimal oversizing ratio for your project based on the capabilities of the SAJ R5, R6, and C6 series.
Beyond the basic power rating, we advise clients to focus on these key performance indicators:
- Max. Efficiency (%): A higher percentage means less energy is lost during DC to AC conversion, directly impacting your ROI.
- MPPTs & String Current (A): Multiple MPPTs offer flexibility for complex roofs. High string current (e.g., 16A) ensures compatibility with modern, high-power bifacial modules.
- Protection Level & Certifications: These determine the inverter's durability (e.g., IP65/IP66) and its compliance with your local grid codes.

자주 묻는 질문
Frequently Asked Questions about our All-in-One Energy Storage Systems.
Beyond the sleek design, the key selling point is "guaranteed system integrity and simplicity." You can tell your clients:
- "This isn't a collection of parts; it's a single, factory-engineered appliance." All components (inverter, battery, BMS) are designed to work together perfectly, eliminating compatibility risks.
- "Installation is faster and cleaner," which often means lower labor costs and less disruption for them.
- "You have a single point of contact for warranty and support," which simplifies their long-term ownership experience.
Frame them as future-proofing investments that deliver immediate or future value:
- For the HS3's EV Charger: "This isn't just a battery; it's a complete home energy hub. You can charge your EV directly with your own solar power, dramatically reducing your transportation fuel costs from day one."
- For the CHS2's VPP Readiness: "For commercial clients, this feature opens up potential future revenue streams. It allows the system to participate in grid services, essentially letting your energy storage asset earn money for you while supporting grid stability."
The "plug-and-play" concept is a significant advantage, particularly with models like the SAJ HS3. While all electrical work must be done by qualified professionals, the pre-integration inside the unit dramatically simplifies the process.
This means less time on-site spent wiring separate components (inverter, battery, BMS, etc.) and troubleshooting communication issues between them. For an installation team, this translates to faster project completion, higher daily installation capacity, and improved profitability.

Frequently Asked Questions about our Smart Accessories.
The best choice depends entirely on the project site's conditions:
- For standard homes with stable Wi-Fi: The eSolar WiFi-D dongle is the most cost-effective, plug-and-play solution.
- For sites with weak Wi-Fi or for critical data reliability: The eSolar AIO3, which supports both Wi-Fi and wired Ethernet, is a more robust choice.
- For remote rural sites or areas without broadband: The eSolar 4G/GPRS cellular dongle is essential to ensure reliable data connection.
- For commercial projects with multiple inverters: The eSolar SEC is the professional choice, enabling centralized monitoring of up to 10+ inverters via a stable RS485 connection.
You should propose an eManager when your client wants to move beyond simple monitoring into active, intelligent energy management. Key scenarios include:
- When they want to integrate their SAJ system with other smart devices, like a heat pump, for coordinated energy savings.
- When they need advanced energy dispatch strategies that go beyond the inverter's standard modes.
- For complex setups involving multiple parallel inverters that require a central "brain" to orchestrate their operation.
While inverters track production, a Smart Meter is crucial for two key business cases:
- Grid Compliance (Zero-Export): In many regions, regulations require limiting or preventing the export of solar power to the grid. A Smart Meter is often mandatory to provide the real-time data needed for the SAJ system to enforce this, ensuring the project is fully compliant.
- Accurate Performance & Financial Analysis: It provides precise data on whole-system energy import and export, which is essential for accurately calculating a project's self-consumption rate, savings, and overall ROI for your client.
This is a critical point, and "close enough" is not good enough. Compatibility issues can cause significant on-site delays. As your sourcing supplier, we address this by:
- Providing you with SAJ's official compatibility matrices for all accessories and inverter/ESS models.
- Verifying your accessory list against your main equipment order before finalizing, ensuring every component is a validated match.
- Guaranteeing that all accessories are genuine SAJ products with the correct firmware versions for seamless integration.
The Smart Wi-Fi Plug is an excellent, low-cost value-add for your residential clients. You can present it as a tool that gives them:
- Granular Control: The ability to remotely manage and schedule high-consumption appliances (like water heaters or pool pumps) to run only when there is surplus solar power.
- Deeper Insight: They can track the specific energy usage of a plugged-in appliance, helping them identify "energy vampires" in their home.
- Enhanced "Smart Home" Experience: It seamlessly integrates into the same eSolar app they use to monitor their main system.
We aim to be your one-stop sourcing solution. Our process includes:
- Holistic Review: When you place an order for an inverter or ESS, we proactively discuss your monitoring and control needs.
- Complete Package Recommendation: We recommend the full suite of necessary accessories (data logger, meter for zero-export, etc.) for your specific project requirements.
- Consolidated Shipping: We manage the logistics to ensure your main units and all smaller accessories are consolidated and delivered together reliably.
