With the rise of distributed energy systems, energy storage is becoming a game-changer in smart energy management. At the heart of these systems is the hybrid inverter, the powerhouse that keeps everything running smoothly. But with so many technical specs, it can be tricky to know which one suits your needs. In this blog, we’ll simplify the key parameters you need to know so you can make a smart choice!
PV-Side Parameters
● Max Input Power
This is the maximum power the inverter can handle from your solar panels. For example, RENAC’s N3 Plus high-voltage hybrid inverter supports up to 150% of its rated power, which means it can take full advantage of sunny days—powering your home and storing the extra energy in the battery.
● Max Input Voltage
This determines how many solar panels can be connected in one string. The total voltage of the panels shouldn’t exceed this limit, ensuring a smooth operation.
● Max Input Current
The higher the max input current, the more flexible your setup. RENAC’s N3 Plus series handles up to 18A per string, making it a great match for high-power solar panels.
● MPPT
These smart circuits optimize each string of panels, boosting efficiency even when some panels are shaded or face different directions. The N3 Plus series has three MPPTs, perfect for homes with multiple roof orientations, ensuring you’re getting the most out of your system.
Battery-Side Parameters
● Battery Type
Most systems today use lithium-ion batteries due to their longer lifespan, higher energy density, and zero memory effect.
● Battery Voltage Range
Make sure the inverter’s battery voltage range matches the battery you’re using. This is important for smooth charging and discharging.
Off-Grid Parameters
● On/Off-Grid Switchover Time
This is how fast the inverter switches from grid mode to off-grid mode during a power outage. RENAC’s N3 Plus series does this in under 10ms, giving you uninterrupted power—just like a UPS.
● Off-Grid Overload Capacity
When running off-grid, your inverter needs to handle high-power loads for short periods. The N3 Plus series delivers up to 1.5 times its rated power for 10 seconds, perfect for dealing with power surges when big appliances kick in.
Communication Parameters
● Monitoring Platform
Your inverter can stay connected with monitoring platforms via Wi-Fi, 4G, or Ethernet, so you can keep an eye on your system’s performance in real-time.
● Battery Communication
Most lithium-ion batteries use CAN communication, but not all brands are compatible. Make sure your inverter and battery speak the same language.
● Meter Communication
Inverters communicate with smart meters via RS485. RENAC inverters are ready to go with Donghong meters, but other brands may require some extra testing.
● Parallel Communication
If you need more power, RENAC’s inverters can work in parallel. Multiple inverters communicate through RS485, ensuring seamless system control.
By breaking down these features, we hope you have a clearer picture of what to look for when choosing a hybrid inverter. As technology evolves, these inverters will continue to improve, making your energy system more efficient and future-proof.
