ملخص
In areas without electricity or frequent power outages, inexpensive solar inverters are widely available. Compared to normal MPPT controllers, our company’s E-Hybrid controllers maximize solar energy use, reduce battery costs, and extend battery life. To give end-users a clearer sense of the product’s advantages, a comparison of the features and cost calculations is presented here.
Detailed Description
1.Normal MPPT controllers
The working block diagram of normal MPPT controllers on the market is as follows:
Its characteristics are:
- The photovoltaic first charges the battery, and then the battery is output to the load;
- Photovoltaic power generation must pass through the battery to the load;
- Can not be used while charging, battery charging and discharging need to be in different periods.
2.E-Hybrid solar controller
E-Hybrid Solar Controller is divided into high-voltage controller and low-voltage controller.
The working block diagram of the high-voltage controller is as follows:
The working block diagram of the low-voltage controller is as follows:
Its characteristics are:
- When the photovoltaic is sufficient, the photovoltaic directly drives the load and charges the battery;
- When the photovoltaic is insufficient, the photovoltaic and the battery drive the load at the same time, and the battery automatically supplements the photovoltaic power;
- When there is no solar and no battery power, you can switch to the mains power.
3. Cost comparison calculation between normal MPPT controllers and E-Hybrid controller
The following table illustrates the cost differences:
Assuming a household requires 3000Wh of energy per day with two 24VDC 300W solar panels and no mains electricity backup, normal MPPT controllers need the battery to discharge for 7 hours during the day and 8 hours at night. في المقابل, E-Hybrid boosters only require 2 hours of daytime battery discharge. Given these discharge requirements, normal MPPT controllers require a 12V 250Ah battery at $357, whereas E-Hybrid controller use a 12V 150Ah battery costing $235. Both batteries have a life cycle of 300 charge-discharge cycles. Under these conditions, the battery in normal MPPT setups lasts only 180 days, whereas in E-Hybrid setups, it lasts 360 days. Consequently, over a two-year period, E-Hybrid setups can save nearly $1000, calculated as follows: $3574 – $2352 = $958.
خاتمة
