Grid-tied solar system with storage
A grid-tied solar system with storage (Hybrid) is a solution that converts solar energy into alternating current to supply electrical equipment that needs uninterruptible power, while storing energy (battery) at the same time. In addition, the excess electricity will be exported to the grid to be sold to EVN
Market demand

- Store excess electricity generated from solar panels for use in the evening or during a power outage

- Ensuring 24/7 uninterruptible power supply for some essential electrical equipment such as medical equipment, security...

 
Application and Principle

- APPLICATION:

+ Households with normal to high monthly electricity bills.

+ For highly electricity-used consumers during the night. Households in areas with frequent power outages affecting daily life or work.

+ The household has installed a grid-tied solar power system and wants to upgrade with the energy storage system.

- Working principle:

+ The system prioritizes using DC power from solar panels to convert to AC power to supply electricity-consuming equipment, and at the same time to charge the battery if the battery has not been fully charged.

+ If the solar system generates excess power, it will be connected to the grid to sell electricity to EVN. When the power from the solar panels and battery is short, the system will automatically draw more electricity from the grid to supply electrical equipment and charge the battery.

+ In case of a power outage or customers disconnecting the system from the grid intentionally, the Hybrid Solar Power System will use power from solar panels and backup power from batteries to supply equipment.

 


 
- OPERATION MODE: There are three basic modes in the PV Master App that end users can use:
+ General mode: During the day, the energy generated by the PV system is used in the following order: supply loads; charge the battery; export excess electricity to the grid. At night, the battery powers the loads. If battery power is insufficient, the system is designed to automatically switch supply sources to the grid to keep the loads energized.
+ Backup mode: In this mode, the battery is only used as a backup power source when there is a power outage on the grid, and as long as the grid is available, the battery will not stop powering the load. The battery will be charged by electricity generated by the PV system or from the grid.
+ Economy Mode: Customers can set charging and discharging times according to the grid's peak and off-peak rates and electricity consumption patterns.
Pros and Cons

- Pros:

+ Ensuring 24/7 uninterrupted power supply: The battery is charged using power solar so that it can ensure 24/7 energy supply for the essential equipment. The system does not depend much on grid power, so when the grid fails to supply energy, the business' operation is not affected.
+ Reduce noise pollution: The system operates automatically and does not require fuels such as gasoline, oil, etc.
Not like normal generators, the system makes no noise or emits pollution while operating.
+ Save on electricity bills: By using solar energy sources, your family, and business can not only power important equipment but also minimize monthly electricity costs.

-Cons:

+ High initial investment cost, mainly for the battery storage system.
+ Take longer to break even - The consultant's profit is higher.
+Installation is more complicated, which requires more space and experienced, specialized construction contractors.
+ Battery lifespan ranging from 7-15 years.
+ Backup power has limitations on the number of devices that can run simultaneously (depending on the Hybrid inverter and its output power limit, quality).

 
Technical Requirements:

Calculate and select equipment in accordance with the needs of the customers: power consumption, load capacity, auxiliary load capacity (back-up load), back-up load power using duration, battery capacity ...

- Ensure compatibility between devices: between panels and inverter, inverter and battery.

- Set proper operating mode, charge and discharge duration to get the highest economic efficiency.

Why you should partner with a reputable supplier?
Currently, there are many products from different brands, from many large and small importers and distributors in the solar power market. There are many suppliers who choose low-end products or compete on price to get the market. However, the lifespan of a solar system can be up to 30 years, so you need to choose a reputable distribution company that has a long-term business strategy in the field of renewable energy to cooperate, to ensure product warranty issues when there is a problem.

A company with a highly specialized technical team is also an important factor in ensuring the best support for your Agents & Partners when cooperating in this high-tech, multi-technical field.
