What information is needed to customize an inverter?

2026-10-12

We need: 1. Required power (kW); 2. Output voltage and frequency (110V/220V, 50/60Hz); 3. Battery voltage type; 4. PV input requirements (MPPT count, max voltage); 5. Communication/monitoring requirements; 6. Brand and packaging requirements; 7. Target market and required certifications.

What is the IP rating? Can it be installed outdoors?

What is the IP rating? Can it be installed outdoors?

Grid-tie inverters typically have IP65 protection and can be wall-mounted outdoors. Off-grid/hybrid inverters are often IP20/IP43 and are recommended for indoor installation in well-ventilated locations or distribution boxes. Ensure adequate ventilation space during installation, avoiding direct sunlight and water immersion.

Is it single-phase or three-phase? What is the power range?

Small residential models are mostly single-phase output (3kW-12kW). Commercial/industrial models are three-phase (10kW to hundreds of kW). Off-grid hybrid inverters typically range from 1kW to 12kW, while grid-tie inverters cover 1kW to 250kW+.

Does the inverter have WiFi monitoring? Is there a mobile app?

Yes, most models come with a built-in WiFi module supporting 2.4GHz WiFi. You can monitor real-time generation, consumption, and battery status via a mobile app (iOS/Android). Some models also support Bluetooth, RS485, and CAN communication.

Can multiple inverters be parallel-connected?

Most hybrid inverters support parallel operation via dedicated parallel cables. Up to multiple units can be paralleled (depending on model, commonly 9+), supporting single-phase and three-phase split-phase output. A dedicated parallel kit is required.

What battery voltages are compatible?

Common battery voltages for off-grid/hybrid inverters are 12V/24V/48V. Models under 3kW are often 24V or 48V; 3kW and above are typically 48V. Some models support automatic battery voltage detection. Grid-tie inverters (battery-less) do not require a battery.

What is the inverter efficiency?

Solar inverter maximum efficiency is typically 97%-99%, with European efficiency around 96%-97%. Pure sine wave output with THD<3%. Please refer to the datasheet of the specific model for exact efficiency parameters.
