As photovoltaics enter more homes, more and more home users will have a question before installing photovoltaics: What kind of inverter should they choose?
When installing home photovoltaics, the following 5 aspects are what you must consider:
01
maximize revenue
What is an inverter? It is a device that converts DC power generated by solar modules into AC power that can be used by residents. Therefore, power generation conversion efficiency is a priority issue when purchasing an inverter. At present, it has become a mainstream trend for domestic households to adopt high-power and high-current components . Therefore, households must first consider inverters adapted to high-current components , which have higher conversion efficiency and lower costs.
In addition, there are several important indicator parameters for comparison:
Inverter efficiency
The maximum efficiency and MPPT efficiency of the inverter are important indicators for considering the power generation of the inverter. The higher the efficiency, the stronger the power generation.
DC operating voltage range
The wider the DC operating voltage range, which means early start and late stop, the longer the power generation time, the higher the power generation.
MPPT tracking technology accuracy
MPPT tracking technology has high accuracy, fast dynamic response, can adapt to rapid changes in illumination, and improves power generation efficiency.
02
Flexible adaptation
The environment of household power stations is relatively complex. Problems such as rural power grid terminals and power consumption will cause inverter AC overvoltage, undervoltage and other alarms. The inverter needs to have weak grid support, a wide grid voltage adaptability range, and overvoltage derating. , reactive power compensation and other functions to reduce fault alarms. The number of MPPTs is also one of the important indicators to be considered: multi-channel MPPT configuration can be flexibly configured according to factors such as different orientations, different roofs, and different specifications of components.
03
easy installation
Smaller and lighter models are easier to install. At the same time, you should choose an inverter that has been set up in the factory before leaving the factory. After it is installed at the user's home, it can be used after powering on, which saves debugging time and is more convenient.
04
safe and stable
Since many inverters are installed outdoors, the IP waterproof and dustproof level is a protection index that cannot be ignored, which can effectively protect the inverter from harmful effects in adverse climate environments. Choose an inverter with IP65 or above to ensure The inverter operates normally.
In terms of protection functions, in addition to necessary functions such as DC switching, input overvoltage protection, AC short circuit protection, AC output overcurrent protection, and insulation resistance protection, there are three other very important functions:
#
DC arc intelligent detection AFCI
It can accurately identify arcing signals, shut down quickly, avoid fire, and protect user safety.
#
Fault recording function
Observe and record the voltage and current waveforms on the AC side of the inverter in real time to quickly locate problems.
#
Smart IV Scanning and Diagnosis
It can accurately locate string faults and proactively discover problems. With multiple guarantees, the power station can operate stably, giving users peace of mind.
05
Smart Management
In today's digital era, intelligent devices can provide users with more convenience. Inverter brands equipped with intelligent management platforms can bring great convenience to users in power station management: First, you can use your smartphone to monitor the power station, check power station operation data anytime and anywhere, and understand the status of the power station in a timely manner. At the same time, manufacturers can discover problems through remote diagnosis, analyze the causes of failures, provide solutions, and solve problems remotely in a timely manner.
