Y&H Renewable Energy Controllers

Y&H Renewable Energy Controllers are a great way to increase your home solar power system's output. These controllers use Fuzzy switching technology to recognize the mode of micro-grid operation and activate the appropriate control set for charging and discharging the battery. They can also detect whether you have five volts of PV on the battery or less. Whether you use a deep-cycle lead-acid battery or a hybrid battery, you can find a controller for your specific needs.

Fuzzy switching controllers recognise the micro-grid operation mode

Y&H renewable energy controllers recognise the micro-grid operation modes by means of a state-chart. These modes are a result of distributed control algorithms. The state-chart input events correspond to different operating modes. They are: (1) and (8), respectively. Then, the controllers reconfigure the micro-grid partition to the desired state-of-charge (SOC).

Fuzzy switching controllers recognise the micro-Grid operation mode by determining the optimal output of the fuel cell/battery DC micro-grid based on the battery voltage and state-of-charge. The controller is programmed with five pre-defined rules to maintain the desired SOC level of the battery banks. It also controls the charging and discharging currents.

Adaptive fuzzy logic control (AFLC) has been developed for autonomous AC microgrid involving renewable energy sources. Renewable energy sources have high degrees of nonlinearity and vary load conditions, affecting the frequency of the system. Fuzzy input and output membership functions are tuned online to account for system operating conditions. Fuzzy switching controllers recognise the micro-grid operation mode of Y&H renewable energy controllers.

Y&H renewable energy controllers recognise the micro-grid operation modes using a rule-based power management system. This power management system consists of 15 distinct operating modes, each corresponding to a state machine approach. During the DC micro-grid mode, DG is used as a backup source, to enhance reliability. The DG is also used to meet AC loads.

They activate the proper control set for charge/discharge of the battery

A good renewable energy controller must be able to recognize the mode of operation of the micro-grid and activate the proper control set for charge/distcharging the battery accordingly. This is possible with Y&H Renewable Energy Controllers. The controller ensures full SoC of the battery and avoids over-charging it. The charger must also be able to prevent overcharging of the battery to increase its lifespan.

The charge controller must have a high voltage limit. This is to avoid overcharging the battery and over-discharging it. A high set point voltage prevents switching disruptions and harmonics. If the battery falls below the set point voltage, the controller will automatically disconnect the load to avoid an under-discharge. Therefore, the charger must be installed on the battery.

The ideal charge/discharge set point depends on the type of battery used in the renewable energy system. In most systems, deep-cycle lead-acid batteries are used. There are two basic types: flooded and sealed batteries. The former uses a liquid filled between the plates while the latter uses a saturated pad between the plates. Sealing makes the battery maintenance-free, but must be regulated to a lower voltage than flooded batteries.

Y&H Renewable Energy Controllers activate and deactivate the proper control set for charge/discharging of the battery. The battery's voltage depends on the electrical load in the home, so when the controller disconnects the PV array, the voltage goes back up. The controller then reconnects the PV array to the batteries, which is when the recharge set-point is reached.

They use deep-cycle lead-acid batteries

Deep-cycle lead-acid batteries are the heart of the solar and wind power system. These powerful batteries store energy at varying rates and are able to withstand high voltages and currents. However, lead-acid batteries are dangerous, especially when they are discharged quickly. It's therefore important to wear protective gear when handling these batteries, as battery acid can burn your skin and eyes.

Lead-acid batteries develop a potential difference between the electrodes, which drives the current. The voltage is then transferred to an external load, such as a solar panel or appliance. The size of the cell, as well as the number of cells, will determine the maximum current deliverable. Ultimately, the Y&H Renewable Energy Controllers use deep-cycle lead-acid batteries to provide the power your home needs.

A deep-cycle battery has many benefits. The chemical reaction on the lead plates is fully reversible, extending its life span. This is a distinct advantage over standard primary batteries, which must be disposed of after one use. A deep-cycle battery will last for more than five years, or even over ten if properly maintained. The battery's cycle life will also depend on how often it is discharged and recharged.

Deep-cycle lead-acid batteries are ideal for solar photovoltaic systems, and are also ideal for electric vehicles. Because they can be discharged to almost zero, they are more environmentally friendly than conventional car batteries. Besides preserving the environment, deep-cycle batteries also have a long life span. And unlike regular batteries, they can be discharged and recharged repeatedly to 20% of their original capacity without losing their power.

A deep-cycle lead-acid battery has two major components: a negative electrode and a positive electrode, and an electrolyte. A negative electrode is made of lead; a positive electrode is made of lead dioxide. Both electrodes are immersed in a sulfuric acid solution. The positive electrode is placed on the opposite side. The latter contains sulfuric acid to provide an electrolyte environment for the chemical reactions.

They have a temperature sensor

Many Y&H Renewable Energy Controllers have built-in temperature sensors to help maximize battery performance and prolong battery life. However, there are some differences in temperature compensation among the controllers. Some use a battery-side temperature sensor, while others use the ambient temperature to ensure proper battery charge. Some batteries are not compatible with temperature sensors. If you plan to use lithium batteries, you should also be aware of the compatibility issues.
