🔋Their main attraction is that they do not require constant maintenance.

🔋They take up less space and are thus more suitable when there are space considerations.

🔋 They do not have to completely discharge before quick recharging, as with some other battery technologies.

🔋 They have very much longer life than other battery types.

🔋Comparatively, Li-ion batteries charges extremely faster than other rechargeable batteries. The reason is because while lead acid batteries require a three stage charging profile where each stage progressively lowers the charge current and can be bulk-charged up to 80%, then absorption-charged from 80% to about 95% and then float-charged to 100%. Li-ion batteries however do not have such a similar three-stage charging and can be bulk-charged all the way up to 100%.

🔋Li-ion batteries can withstand very rugged power conditions than other type of batteries. They can supply electricity to very high power appliances. Under the same conditions, LIB are far more efficient than lead acid batteries.

🔋 Lead acid batteries only have a charge efficiency of 85%. This means that for every 1A sent to the batteries, only .85A are stored for use. Lithium batteries however have a charge efficiency of 99% so nearly every amp sent to them is stored and usable. 🔋Therefore, a lead acid battery bank will require a 15% larger – and more expensive – solar array to charge it as fast as a comparably sized lithium battery bank.

🔋 The lifespan of lithium batteries is significantly higher than that of normal lead acid batteries! Some manufacturers warranty their Li-ion batteries to last 10,000 cycles. Most lead acid batteries are only rated for 400 cycles or less. This means li-ion batteries will last ten times longer than their lead acid counterparts! In addition,

🔋 deeper discharge levels reduce the number of cycles from lead acid batteries. Li-ion batteries are less affected by deep discharge.

Airborne dust particles, sticky tree and plant sap, lichen, soot and bird droppings are just a few of the things that can contribute to a build-up of dirt on your solar panels. These dirt accumulations can unfortunately create cellular shading on the panels, preventing sunlight from reaching the cells. This results in poor system performance, a loss of efficiency for the owner of the solar energy system. Poor charging current from the solar panels can lead to insufficient charging of the solar-inverter batteries which may reduce the lifespan .

1) VOLTAGE SPIKE DUE TO LIGHTING /THUNDER STRIKE AND POWER SURGE : Voltage spikes can also damage inverters. These occur when the voltage in the power supply suddenly rises above the normal level. This can happen due to lightning strikes, power surges. To protect your inverter from voltage spikes, you should use thunder arrestor, surge protectors and voltage regulators.

2) POWER SUPPLY PROBLEMS (GRID(NEPA)/ GENERATOR): problems with the power supply can also damage inverters. This can happen if the voltage is too low or too high, or if the power supply is unstable. To avoid power supply problems, make sure that you use a high-quality AUTOMATIC VOLTAGE REGULATOR (AVR) or Stablizer that is designed for use with your inverter.

3) OVERHEATING : Finally, Inverters generate heat when they operate, and if they get too hot, they can be damaged. This can occur if the inverter is installed in a location that gets too much sun or if it is placed in a confined space with poor ventilation. To avoid overheating, make sure that your inverter is installed in a well-ventilated area and the internal fan is working as expected.

Benefits of an MPPT Solar Charge Controller

The efficiency and performance of your solar-Inverter setup significantly increase when you use an MPPT controller. It yields numerous benefits that help you save money and recoup your initial investment in your solar power system more quickly.

The benefits are:

💎More Efficient Power Transfer

Either type of solar charge converter affects the electric current from solar panels to the battery. The current is critical since the battery can only hold so much power at a time. Sending too wide a current to the battery will mean most of the energy is lost. But because the MPPT manages the voltage and the amperage, it allows your system to store more of the rated wattage for your solar panels. 

Greater efficiency is critical to getting the most from your system and meeting your electricity needs from your solar power array.

💎Less Dependent on Weather

A key to solar power effectively meeting your energy needs is storing energy to use when the sun isn’t shining on your solar panels. 

On cloudy days, the maximum power point changes throughout the day. The more time you miss that optimal balance, the less effectively your system can operate. The MPPT controller adjusts to environmental changes and helps your system maintain the best possible output.

💎More Effective for Large Systems

As your system grows, getting better output from each solar panel becomes more critical. For multiple-panel solar arrays, the difference can become staggering. 

Given the inevitable energy loss from the time the sunlight hits your panels to the power running through your system, improvements for each panel pay substantial dividends across your array and over time. Using an MPPT controller for large sets of panels will significantly amplify the power you can access and use.

💎Return on Investment

An MPPT solar charge controller costs more than a PWM controller. What you give up in up-front cost, though, you gain in functionality. 

When you consider any solar energy system pays dividends through reduced energy costs and a much smaller carbon footprint that you leave behind, an MPPT solar charge controller helps you realize these benefits. It lets you receive the benefits sooner and more completely than its rival PWM controller. 

Conclusion 

MPPT solar charge controller gives you significant advantages that pay off over time. It lets you get the most out of your system, avoid lost energy, and maintain peak delivery throughout the year. 

The more efficiently you generate and store energy, the more quickly your initial investment will pay off financially. An MPPT solar charge controller gets you to a positive ROI more quickly.

MPPT (Maximum Power Point Tracking) controllers are crucial in solar power systems because they optimize the efficiency of energy conversion by continuously adjusting the solar panel's operating point to extract the maximum power available from the sunlight. This results in increased energy production, improved system performance, and better return on investment for solar installations.

The main difference between MPPT (Maximum Power Point Tracking) and PWM (Pulse Width Modulation) controllers lies in how they regulate the charging of batteries in solar power systems.

1. MPPT Controller:

  - MPPT controllers continuously track the maximum power point of the solar panel array, adjusting the voltage and current to ensure maximum power is harvested from the sunlight.

  - They are more efficient than PWM controllers, especially in conditions like cloudy weather or varying sunlight intensities.

  - MPPT controllers are generally more expensive but offer higher energy yields over time.

2. *PWM Controller:

  - PWM controllers regulate the charging of batteries by rapidly switching the solar panel's voltage between the battery's voltage and the open-circuit voltage.

  - They are simpler and less expensive than MPPT controllers but are less efficient, especially when the solar panel voltage is much higher than the battery voltage.

  - PWM controllers are suitable for smaller solar power systems or applications where cost is a significant factor and energy efficiency is less critical.

In summary, while both types of controllers manage the charging of batteries in solar power systems, MPPT controllers offer higher efficiency and better performance, especially in variable conditions, but come at a higher cost compared to PWM controllers.

1. Avoid deep discharging. Turn off the inverter before the battery completely drains.

2. Prevent excessive battery depletion by switching off the inverter before it shuts down due to low voltage.

The primary differences between hybrid and non-hybrid inverters lie in design, functionality and reliability.

Hybrid Inverters:

1. Transformerless or transformer-based

2. Integrated inverter and charge controller

3. ⁠Super efficient

3. Efficient MPPT charge controller

4. Detailed monitoring capabilities

5. Smart operation

6. Drawback: Repair challenges (50% success rate) and battery charging issues if faulty due to the inbuilt charge controller.

Non-Hybrid Inverters:

1. Mostly transformer-based

2. Separate charge controller required

3. Efficient and rugged

4. Easier repair (less impact on battery charging)

5. When faulty , it doesn’t prevent charging of battery from the solar panel due to the external charge controller.
