☀️ High-Voltage Solar Input
One of the major advantages of the IVEM4024 II is its high-voltage PV input capability.
A maximum solar input voltage of up to 500V DC allows multiple solar panels to be connected in series, which can:
- Reduce PV cable current
- Reduce voltage drop over longer cable runs
- Allow cleaner solar-array wiring
- Improve flexibility when configuring larger solar arrays
- Reduce the number of parallel PV strings required
The final solar-panel configuration must still remain within the inverter's approved MPPT voltage range, maximum PV current and maximum PV power.
🔋 24V Battery System
The inverter operates using a 24V battery bank.
Depending on the inverter charging configuration, it may be paired with compatible:
- 🔋 LiFePO₄ lithium batteries
- 🔋 Gel batteries
- 🔋 AGM batteries
- 🔋 Deep-cycle lead-acid batteries
Typical configurations may include:
- One compatible 24V lithium battery
- Two identical 12V batteries connected in series
- Larger 24V battery banks for increased backup duration
Battery charging parameters should always be matched to the specific battery chemistry.
🌊 Pure Sine Wave Output
The inverter provides pure sine wave power, making it suitable for sensitive electronics and many motor-driven appliances.
Benefits include:
- Stable AC output
- Reduced electrical noise
- Better compatibility with electronics
- Improved operation of motors and compressors
- Safer operation of computers and communication equipment
✅ Benefits
- Powerful 4kW output
- High-voltage PV input
- 24V battery architecture
- Pure sine wave output
- Combines solar, grid and battery operation
- Compact wall-mounted design
- Suitable for larger residential solar arrays
- Supports a broad range of household loads
- Suitable for lithium and conventional battery systems when correctly configured
⚠️ Solar Panel Configuration
Because this inverter accepts PV voltage up to 500V DC, solar-panel string sizing must be done carefully.
Before connecting panels, confirm:
- ☀️ Maximum PV open-circuit voltage
- 🔆 MPPT operating voltage range
- ⚡ Maximum PV input current
- 🔋 Maximum permitted solar-array wattage
- 🌡️ Cold-weather Voc increase of the panels
- 🔌 Correct DC isolator and surge protection requirements
The combined Voc of panels connected in series must never exceed the inverter's maximum PV voltage.
