FAQ
What services does Hypon offer?
Our service includes inverter product service and smart energy management solutions. Remote technical support is provided by Hypon HQ service team and exchange service is provided by local distributors or installers. They can help you with PV system design and installation as well. Any inquiries you can write to Hypon service or go by online claim.
What equipment does the commercial solar power system include?
Basic configuration: solar panel, inverter, bracket, cable and installation accessories, etc. For large power plants, transformers, distribution cabinets and other auxiliary equipment are also required.
Does a household PV system need energy storage equipment?
Generally use the PV grid-tied system, but in the following areas we recommend the use of home energy storage system:
1. Remote areas: remote areas are often unstable power supply or difficult to access the traditional power grid, home energy storage system can provide a stable power supply in these areas, to meet the basic needs of the residents of electricity.
2. Areas with high electricity costs: The home energy storage system can be combined with the family's photovoltaic system to realise the self-generation and self-consumption mode of electricity. In sunny times, photovoltaic system generated power can be stored in the storage system, and then in the evening or cloudy days when the photovoltaic system can not generate power, the storage system can be discharged to meet the family's power needs. This not only reduces the family's electricity bill, but also reduces dependence on the grid.
3. High electricity price difference areas: In some areas with large electricity price differences, the energy storage system can be used through the peak/valley arbitrage mode to store electricity at lower prices and use the stored electricity at higher prices, thus reducing electricity expenses.
What size is the installation area of a solar power system?
It depends on the actual area available on your roof. Generally, 10 square meters are required for a 1 kW system.
Can a distributed photovoltaic power generation system be installed in commercial housing?
Yes. You need to explain the situation to the residents in your building and the property management department. The application form needs to be signed by the residents and sealed by the property management department, which will then be archived as a grid-connected application.
What happens when the grid is undervolted?
Turn the Multimeter onto AC voltage gear, measure the AC output terminals should have 220V or 380V voltage, if not, check in turn whether the terminals are loose, whether the AC switch is closed, whether the protector switch is disconnected. If the customer is using a hybrid energy storage inverter, when the grid is cut off, the hybrid energy storage inverter will switch to off-grid mode.
What communication protocol does the inverter use?
Typically, serial-based communication uses the Modbus-RTU communication protocol.
How long is the warranty of the new replaced inverter after the original inverter been replacement?
The warranty period will not be interrupted or extended by product repair or exchange, and the replaced machine or equipment will automatically inherit the remaining warranty period of the whole machine or equipment before replacement.
Does the inverter fan need to be cleaned regularly?
Our inverter fan is maintenance-free mode, so there is no need to clean them when there is no fan alarm.
The inverter display shows that the panel insulation impedance to ground is too low, what is the reason? How to solve it?
The inverter detects that the PV+ and PV- to ground insulation impedance on the group inspection side is too low, according to the safety regulation, the inverter must stop working, otherwise it will produce the risk of electric shock.
1. Use resistance shake table to detect whether PV+ to ground and PV- to ground insulation resistance is less than 2M ohms, which can be determined to be caused by the string group problem.
2. If there is another inverter on site, you can exchange the inverter and then check the inverter status, if the fault follows the inverter transfer, then it can be confirmed that it is an inverter fault, if the fault doesn't follow the inverter transfer, then check the PV string of the original inverter.
3. Turn off the inverter switch , unplug the PV terminal connected to the inverter, try to input one group of strings at a time to the inverter and then grid connect, if a group of strings alone to the on grid there is an error, you can determine the string problem, check whether the problem string has broken skin cable, PV terminal into water and other problems.
