Solar inverter datasheets, manuals, warranty references, and technical FAQs

Start with the document that matches the decision stage. Sending the wrong file to procurement is a common cause of second-round clarification, so use this order:

• Datasheet — use this first when the buyer is still comparing family, power range, phase, MPPT layout, efficiency, or battery fit. It gives the numbers the shortlist is built on.
• User manual or quick guide — move to this when the installer needs wiring, commissioning steps, protection settings, or operational detail.
• Warranty statement — request this once the model is shortlisted and the buyer needs coverage terms, service scope, or warranty registration steps for approval.

Each product family block below links directly to the current document packs so you can download the matching set in one pass.

The right choice depends on what the system must do after the panels convert sunlight, not just on panel size. Use this comparison to guide the conversation:

If the buyer is unsure whether the site needs backup loads, ask for the critical-load list and backup duration target before locking the family.

All three are SAJ string on-grid inverters, but they sit at different power levels and use cases. Matching the series to the project scale prevents under-sizing and unnecessary cost:

R5 Series

0.7–12 kW, single-phase and three-phase options, residential to small commercial. Compact, quiet, and widely used where roof space and noise matter.

R6 Series

15–50 kW three-phase, aimed at commercial rooftops, small C&I, and distributed projects that need higher current capacity and wider MPPT voltage windows.

C6 Series

50–70 kW three-phase, built for larger commercial and light industrial arrays where string count, grid support, and robust enclosure ratings are priorities.

If you only know the AC output target and roof size, share those two numbers and Sunriver can narrow the series in one reply.

A clear brief cuts the shortlist from a full catalog to two or three models. Include these points in the first message:

1. Application — residential, commercial rooftop, C&I, carport, or off-grid/backup.
2. AC output target — desired kW or kVA per phase.
3. Grid type — single-phase or three-phase, nominal voltage, and destination country.
4. Battery requirement — yes/no, expected chemistry (LiFePO4 is standard for SAJ hybrids), and backup duration if applicable.
5. Monitoring preference — Wi-Fi, Ethernet, 4G dongle, or third-party portal integration.
6. Expected quantity and timeline — helps confirm stock, lead time, and packaging.

Send the details through the technical compatibility form or the quote request page.

SAJ hybrid inverters are designed around LiFePO4 battery chemistry because of its thermal stability and long cycle life. The acceptable voltage window depends on the inverter platform and power class:

• H1 / H2 single-phase hybrids — typically 90–550 V or 180–800 V battery ranges, depending on model; check the exact datasheet before pairing.
• H2 three-phase hybrids — commonly 180–900 V, suited to larger residential or small C&I battery racks.
• HS2 / HS3 all-in-one ESS — ship with matched battery modules; use the factory-approved battery set to keep warranty and BMS communication intact.

Do not assume two LiFePO4 batteries with the same nominal voltage will communicate correctly. The BMS protocol, CAN/RS485 mapping, and charge-current limits must match the inverter model. If the project already has a preferred battery brand, send the model name before finalizing the inverter.

Compatibility questions are cheapest to resolve before the buyer locks the model list. Ask for confirmation when any of these apply:

• The project includes hybrid storage or backup loads.
• The installer plans to use a third-party battery instead of the factory-matched ESS pack.
• The site needs meter integration, export limiting, or zero-export control.
• The buyer wants accessory matching — meters, dongles, surge kits, or monitoring gateways.
• The destination country has grid-code or certification requirements beyond the standard datasheet listing.

For these cases, use the technical compatibility form and attach the battery datasheet or single-line diagram if available.

SAJ systems are monitored through the SAJ Elekeeper platform. Depending on the inverter, data reaches the app over Wi-Fi, Ethernet, or an optional 4G dongle.

After the system is online, the app shows:

• Plant dashboard — live power, daily energy, and system status.
• Inverter detail view — PV voltage, current, grid parameters, and fault flags.
• History — daily, monthly, and yearly production curves.
• Alerts — fault notifications and maintenance reminders.

On some models you can enable “Real-Time Data” from the top-right menu inside the Plant screen to refresh more frequently. If the dashboard shows zero production or stale data, check the communication LED on the inverter and confirm the site router is allowing outbound traffic. For a deeper first-check guide, see SAJ Elekeeper: Monitoring, Alerts, and Setup.

Most fault codes on SAJ inverters fall into a few groups. The exact code is shown on the LED display or in the Elekeeper app. Use this as a first-response guide:

For any fault that repeats after a power-cycle, note the model, code, and site voltage, then open a support request through the form below.

Warranty documents are treated as part of the procurement file, not the marketing file. The standard workflow is:

1. Download the family document pack from the section below to review product coverage in principle.
2. Request the exact warranty reference for the final model and destination market once the shortlist is approved. Warranty terms can vary by region and by optional extension.
3. Register the installation through the SAJ warranty portal or distributor channel within the required window. Late registration can reduce or void coverage.

If the buyer needs service planning detail — such as RMA routing, spare-part lead time, or local service partners — include that in the technical support request so the right document can be attached.

Yes. Sunriver supports the technical review stage before the order is placed and after delivery during first commissioning. The typical path is:

• First pass — use the videos, datasheets, and quick guides in the family document packs below.
• Model matching — send the project type, AC target, phase, and destination country for a shortlist recommendation.
• Compatibility check — share the battery model, meter type, or single-line diagram for a pairing confirmation.
• Commissioning support — describe the symptom, fault code, or commissioning step that is blocked, and the team will route it to the right technical reference.
