What is the TBB collection?
The TBB collection brings together complete solutions for off-grid and backup solar systems: RiiO Sun II inverter-chargers (single and three-phase via parallel kits), MPPT charge controllers SP series, modular 48 V lithium batteries (rack format), and supporting electronics (monitors, meters, and DC combiner boxes). It is designed for residential and professional installations that require service continuity, future expansion, and reliable monitoring.
Advantages and limitations
- All-in-one architecture in RiiO Sun II: inverter, AC charger, and integrated MPPT (depending on model).
- TBB SP MPPT with high PV threshold (150/250 V models) for flexible strings and better solar utilization.
- Parallel/three-phase options and communication accessories for remote management.
- LiFePO₄ 48 V rack batteries: clean installation, integrated BMS, and scalability by modules.
- Limitations: follow compatibility tables, charge curves, and Voc/Isc limits per MPPT.
Applications
- Off-grid homes with inverter-chargers and 48 V lithium battery banks.
- Backup for SMEs, telecom, and pumping with fast switching and load prioritization.
- Modular systems expandable to three-phase via parallel kits and 19” rack cabinets.
How to choose within TBB
- Power and phase: select VA/kW and whether you need 1P or 3P (parallel) according to your panel and start-up peaks.
- MPPT: define maximum panel voltage (Voc in cold) and current per input; choose 150/250 V according to your string.
- Battery: size usable energy (kWh) and BMS discharge power; prioritize 48 V for modern installations.
- Management: add monitor, gateway, or bidirectional meter to optimize generator/grid use.
Indicative specifications
| Inverter-chargers | RiiO Sun II (1P/3P via parallel), AC charger and integrated MPPT in S-MPPT models |
| MPPT controllers | SP series (typical PV thresholds 150/250 V, 12/24/48 V battery) |
| Batteries | 48 V LiFePO₄ lithium in rack, stackable modules with BMS |
| Communication | Interfaces and gateways for monitoring and configuration |
| Accessories | DC combiner boxes with protections and parallel/three-phase kits |

Best practices
- Design strings respecting Voc at minimum T°C and the current/MPPT allowed; protect PV and battery with DC protections.
- Separate critical loads in a sub-panel and verify the inverter’s continuous and peak power.
- Adjust charge curves according to battery type; for lithium, enable BMS-inverter communication when available.
- Complete the installation with suitable AC protections, solar cable, and electrical panels.
