Mid-Sized Commercial Rooftops
Who it’s for: Clinics, schools, and warehouses with daytime loads and 3-phase utility access.
Why this inverter fits:
- Three-phase output for grid balance and energy stability
- 6 MPPT inputs – ideal for complex multi-azimuth installations
- 150% DC/AC oversizing – supports more PV in less space
“Used this model to power our 20kW rooftop array across two buildings. Smooth install.” — Installer, Ayutthaya
Urban Rooftop Upgrades (Export-Limited)
Who it’s for: Residential users with three-phase access but restricted feed-in permissions.
Why it’s the smart choice:
- Compact size for side-wall installs, even up to 12kW
- Export limitation via Modbus meter support
- Quiet operation + full app-based monitoring
Popular in suburban Thailand, Vietnam, and Eastern Europe where households want large rooftop PV arrays without violating grid export limits.

Frequently Asked Questions
Find answers to common questions about our products and services
What certifications does the R5-3k~12k-T2-15 meet for international use?
📄 Where It’s Accepted
| EN 50549-1 | Europe (general grid compliance) |
| G99 | United Kingdom (three-phase systems) |
| CE / EMC / LVD | EU-wide safety and emissions |
📝 Useful Tip
Most installers submit these certificates when applying for grid tie-in, rebates, or FIT programs. If you’re working with a local DSO, keep the PDFs handy—they’re typically requested early in the process.
What kind of PV modules does this inverter support?
⚙️ Specs at a Glance
- MPPT range: 160–1000V
- 16A per string input current
- 3 MPPTs / 6 strings – ideal for complex roofs
✅ Best Fit Modules
Works well with 182mm and 210mm half-cut monocrystalline panels in the 450–600W range. Great for bifacial panels too.
Oversizing up to 150% is allowed—meaning a 10kW inverter can handle 15kW of PV for better performance on cloudy days.
How can I track system performance and update firmware?
📲 Live Monitoring Options
- SAJ eSolar App (mobile): shows real-time power, history, alerts
- Installer Portal (web): manage multiple sites from one place
- Wi-Fi standard, 4G stick optional for off-grid sites
🔧 Firmware Without the Truck Roll
OTA (Over-the-Air) updates mean your system can stay current without needing an engineer on-site. Installers can schedule upgrades via the portal with just a few clicks.

🤝 What We Don’t Do
We do not offer installation or post-sales maintenance. Our focus is clear: help installers and distributors get quality stock, fast and with no surprises. If that’s your workflow—we’ll work great together.
Can I limit export power for self-consumption setups?
🔄 Yes, Here’s How
This inverter supports export limitation using an external Modbus-compatible energy meter. It’s especially useful in regions where export is restricted or for customers looking to maximize self-use.
📋 Configuration Summary
- Function: Dynamic power throttling based on grid export
- Hardware: External energy meter required
- Communication: Modbus RTU via RS485
How noisy is the R5 inverter during operation?
🔈 Noise Profile (by Model)
| 3–8kW Models | Natural convection (no fan), under 25 dB |
| 10–12kW Models | Ultra-quiet fan, max ~35 dB at full load |
🏡 Installation Advice
- Garage or balcony? No problem—it’s quieter than a fridge.
- No transformer hum: transformerless design
- For rooftop mounting, no noise transfer to rooms below
If your client values quiet operation in residential or light-commercial zones, this model fits the bill without compromise.
