Felicity Solar 16kW 3-Phase 48V Low Voltage Hybrid Inverter

FAQ

Q1: Is the Felicity Solar 16kW inverter a low-voltage or high-voltage system?

This is a low-voltage (48V) hybrid inverter. It does not use high-voltage (HV) battery stacks. Instead, it requires multiple 48V batteries connected in parallel to safely support its high power output.

Q2: How many batteries are required for safe operation?

Because the inverter can draw up to 300A at 48V, a large battery bank is essential.

As a guideline:

• Absolute minimum: ±20kWh (not recommended for high loads)

• Practical minimum: 30–40kWh

• Ideal for full 16kW usage: 40–60kWh

Using too few batteries will cause:

• Battery overcurrent stress

• Voltage sag

• Inverter shutdowns

• Shortened battery lifespan

Q3: Can I use lithium batteries from different brands?

It is strongly recommended to use:

• The same battery brand

• The same capacity

• The same age

Mixing different batteries can cause imbalance, BMS faults, and uneven charging/discharging. If mixing is unavoidable, professional system design and configuration are required.

Q4: Does this inverter support 100% unbalanced three-phase loads?

Yes. One of the biggest strengths of the Felicity Solar 16kW inverter is 100% unbalanced three-phase output.

This means:

• One phase can carry more load than the others

• Loads do not need to be evenly distributed

• Ideal for real-world homes, farms, workshops, and offices

Q5: What does “EPS output” mean on this inverter?

EPS (Emergency Power Supply) is the backup output that remains powered during grid failures.

When Eskom fails:

• The inverter switches to battery + solar

• EPS circuits stay live

• Critical loads continue running

Changeover is fast and suitable for most appliances and equipment.

Q6: Can this inverter work completely off-grid?

Yes. The Felicity Solar 16kW hybrid inverter can operate in:

• Grid-connected mode

• Hybrid (grid + battery + solar)

• Off-grid mode (no grid connection)

When off-grid, correct battery sizing and solar array design are critical.

Q7: How much solar power can I connect to the inverter?

The inverter supports up to:

• 25.6kW of solar PV

• 1.6× PV oversizing

It has:

• 2 MPPT trackers

• 4 string inputs (2+2)

This allows flexible array design and excellent performance in morning, afternoon, and cloudy conditions.

Q8: What solar panel wattages work best with this inverter?

This inverter works very well with:

• 550W – 610W solar panels

• Long string configurations

• High-voltage MPPT designs

Because of the 800V max PV voltage, installers can build efficient long strings without excessive parallel connections.

Q9: Can I connect a generator to this inverter?

Yes. The Felicity Solar 16kW hybrid inverter supports generator input.

The generator can:

• Power loads

• Charge batteries

• Act as backup when solar is insufficient

Generator parameters must be configured correctly in the inverter settings.

Q10: Does this inverter allow time-of-use (TOU) control?

Yes. Time-of-Use scheduling allows you to:

• Charge batteries at off-peak times

• Discharge during peak tariff periods

• Reduce electricity costs

This is especially useful for businesses and high-consumption households.

Q11: Can multiple inverters be connected together?

Yes. Up to 10 Felicity Solar 16kW inverters can be connected in parallel.

This allows system expansion up to:

• 160kW total output

• Shared battery banks

• Large commercial and industrial systems

Q12: Is the inverter suitable for outdoor installation?

Yes. The inverter is rated IP65, meaning it is protected against dust and water jets.

However:

• Avoid direct sunlight where possible

• Ensure adequate ventilation

• Mount on a solid surface

Outdoor installation should always follow manufacturer guidelines.

Q13: What monitoring options are available?

The inverter includes:

• Built-in LCD touchscreen

• WiFi connectivity

• Felicity Solar Cloud monitoring

This allows:

• Real-time performance tracking

• Remote diagnostics

• Historical energy reporting

Q14: What protections are built into the inverter?

The Felicity Solar 16kW inverter includes extensive protection features:

• AC over-current protection

• AC over-voltage protection

• DC reverse polarity protection

• Ground fault detection

• Insulation monitoring

• AFCI (arc-fault protection)

• Surge protection

These safeguards protect the inverter, batteries, and connected equipment.

Q15: Is this inverter suitable for small residential homes?

Generally no, unless the home has:

• Very high loads

• Three-phase supply

• Large battery storage

• Planned future expansion

For typical homes, smaller inverters are usually more cost-effective.

Q16: What are common mistakes to avoid with this inverter?

Common issues include:

• Undersized battery banks

• Incorrect cable sizing

• Poor ventilation

• Incorrect PV string design

• Ignoring phase balancing

Professional design and installation are strongly recommended.

Q17: What type of installation is required?

This inverter must be installed by:

• A qualified solar installer

• A registered electrician

• In compliance with local electrical regulations

A Certificate of Compliance (CoC) is required in South Africa.

Q18: What warranty does the inverter carry?

Warranty is typically 5–10 years, depending on Felicity Solar’s regional policy and registration requirements. Always confirm warranty terms at time of purchase.

Q19: Who should consider this inverter?

This inverter is ideal for:

• Large homes with three-phase power

• Farms and agricultural systems

• Workshops and factories

• Offices and commercial buildings

• High-load backup power applications

Q20: Can this inverter feed power back to the grid?

This depends on:

• Local grid regulations

• Inverter configuration

• Municipal approval

Always confirm grid-feed compliance requirements before enabling export.
