FAQs
Frequently Asked Questions about our Hybrid Inverters.
A Hybrid Inverter is the superior choice when your client's primary goals include:
- Maximizing Solar Self-Consumption: Especially if their energy usage is high in the evenings, or if local grid export tariffs are low.
- Ensuring Power Security: If they experience frequent grid outages or have critical loads that require uninterrupted power (UPS-level backup).
- Optimizing Energy Costs: If they are on a Time-of-Use (TOU) electricity tariff, a hybrid system can perform "peak shaving" to significantly reduce bills.
We can help you analyze your client's usage patterns to financially justify the upgrade from on-grid to hybrid.
You're right, this is critical. True compatibility goes beyond just matching voltage. The key is ensuring seamless communication between the inverter's Energy Management System (EMS) and the battery's BMS.
This is why sourcing through an authorized channel is vital. We provide SAJ's official approved battery lists for the H1, H2, and H2 LV series. We strongly recommend using these validated combinations to guarantee optimal performance, efficiency, and system safety, avoiding costly on-site troubleshooting.
Beyond the basic "lower your bill," focus on quantifiable, long-term value:
- Calculate the "Cost of Not Having Backup": What's the financial impact of one power outage on their business or home?
- Demonstrate TOU Savings: Show them a clear calculation of savings by shifting just a few kWh of peak usage to stored battery power daily.
- Highlight Future-Proofing: Mention rising electricity prices and how a hybrid system provides long-term cost stability.
We can provide ROI calculation templates to help you build a compelling financial case for your clients.
This choice impacts system design and cost:
- High Voltage (HV) Systems (like SAJ H1/H2): Are generally more efficient in their battery charge/discharge cycle and often allow for simpler wiring with smaller gauge cables. They are excellent for high-performance residential and commercial applications.
- Low Voltage (LV) Systems (like SAJ H2 LV): Offer greater flexibility by being compatible with a wider range of cost-effective 48V batteries, including traditional Lead-Acid. The H2 LV series is also ideal for projects requiring parallel connections or generator integration.
As your sourcing supplier, we ensure that every genuine SAJ Hybrid Inverter is backed by the full SAJ manufacturer's warranty (typically 5-10 years).
In the event of an issue, we act as your direct point of contact to facilitate the warranty process with SAJ, providing clear guidance and support to help you resolve your client's issues efficiently. This reliable after-sales channel is a key part of the value we provide.
We understand hybrid systems require more detailed planning. We streamline the process by:
- Verifying Compatibility: Ensuring the hybrid inverter and any associated components are a validated match.
- Providing Complete Documentation: Supplying all necessary datasheets, manuals, and certifications for both inverter and recommended batteries.
- Managing Logistics: Coordinating the shipment of these high-value systems to ensure safe and timely delivery.

FAQs
Frequently Asked Questions about our All-in-One Energy Storage Systems.
- "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.
- 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."
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.
A client can begin with a 10kWh system to fit their current budget and needs, and then easily add another 5kWh or 10kWh module in a few years if their energy consumption increases (e.g., they buy an EV). This flexibility is a powerful selling point.
- LFP Battery Chemistry: They use Lithium Iron Phosphate (LFP), the safest and most thermally stable mainstream lithium-ion chemistry available.
- Advanced BMS: A multi-layered Battery Management System constantly monitors and protects against all potential electrical faults.
- Integrated Fire Protection: Premium models like the HS3 and CHS2 include additional safety measures like internal self-heating (for performance in cold) and even cabinet-level fire detection and suppression systems.
- International Certifications: These systems are certified to stringent international safety standards (e.g., CE, VDE, etc.).
- Providing Clear Configuration Details: We ensure you have all the necessary datasheets for the integrated inverter, battery, and BMS, so you can design with confidence.
- Ensuring Validated Compatibility: We only supply complete, factory-approved system configurations.
- Streamlining Your Procurement: We manage the sourcing and international logistics of these larger, single-unit systems to ensure they arrive safely and on schedule for your projects.

FAQs
Frequently Asked Questions about our Smart Accessories.
- 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.
- 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.
- 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.
- 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.
