What is the Solax collection?
The Solax collection brings together solutions for self-consumption and storage: X1 single-phase and X3 three-phase grid inverters, hybrid inverters with battery input (HV and 48 V), microinverters, modular lithium batteries (Triple Power and T-S series), meters/CT for zero export, and EV chargers. Its aim is to integrate generation, storage, and intelligent monitoring in a single environment.
Advantages and limitations
- Wide range of power ratings and topologies (grid/hybrid, single/three-phase), with commissioning via app.
- Native compatibility with Solax batteries (HV and LV) and measurement accessories for dynamic load management.
- Fast back-up functions (depending on model) and remote firmware updates.
- Limitations: follow inverter-battery compatibility tables and string sizing to avoid out-of-range conditions.
Applications
- Residential with single-phase inverters and battery option for night-time consumption.
- Light commercial with three-phase and active/reactive power control.
- Hybrid systems with inverters with charger and selective or total back-up.
- Integration with electric vehicle chargers to manage surplus energy.
How to choose your Solax equipment
- Topology: grid only (greater simplicity) or hybrid (add battery now or in the future).
- Phase and power: X1 for 1P (e.g., 2–8 kW); X3 for 3P (e.g., 3–30 kW+). Adjust to consumption and PV surface area.
- PV input: check Voc and Isc per string and number of available MPPTs.
- Battery: HV (high voltage) or LV (48 V) depending on the hybrid. Size according to useful daily energy (kWh) and discharge power.
- Measurement: add meter/CT for zero export and phase balancing if applicable.
Indicative specifications
| X1 inverter power | ≈ 2–8 kW single-phase (depending on series) |
| X3 inverter power | ≈ 3–30+ kW three-phase (depending on series) |
| MPPT | 1–3 MPPT, with input currents suitable for modern modules |
| Battery compatibility | Hybrid models for HV or 48 V (Triple Power / T-S) |
| Communication | App/portal, Wi-Fi/LAN, integration with meters and CT |
| Functions | Backup (depending on model), export limitation, time scheduling |
Best practices
- Design strings respecting Voc at low temperature and maximum current per MPPT.
- For hybrids, verify back-up power and critical loads on the back-up panel.
- For batteries, consider cycles/day and reserve: use DoD and margin for power peaks.
- Complete with suitable DC protection, AC protection, and solar cable.
