MPPT Off Grid Solar Inverter
The name says it all – an inverter that has an in-built DC-to-DC converter is an MPPT solar inverter. There are huge risks of installing a solar inverter that doesn’t use a Maximum Power Point Tracker, the biggest risk being – solar panels won’t work at their maximum efficiency.
Some of the best, tier-1, MPPT solar inverters you can invest in are:
Waaree, 4.5 KW Single Phase Solar On Grid Inverter
LUMINA-15K~25KTL3X
Delta energy, Orion 80 Plus
Benefits of MPPT solar inverter
Any on-grid string solar inverter these days isn’t built without MPPT technology. The reasons that are also the benefits of this technology have been summarized below.
1.It increases the running time of the appliances
2.It helps in generating greater power from solar panels
3.It reduces power wastage by directing extra power to the grid in a grid-tied solar system
4.It uses excess power to charge the battery in case of an off-grid solar system
Even if there’s any inefficiency in the appliance connected to the inverter, MPPT doesn’t let it affect the efficiency of the solar panels.
Either way, whether for an off-grid system or an on-grid system, the MPPT technology minimizes power wastage and maximizes the power generation from solar panels.
Key points about MPPT on-grid inverters:
What it does: Continuous tracking of the voltage and current at the solar panels using an algorithm to find the MPP or “maximum power point.” The algorithm then optimizes the input voltage to the inverter such that the panels run at this MPP, giving the best possible energy production.
Advantages:
Higher energy production: Because of optimized output power, MPPT technology maximally improves the efficiency of any solar system, resulting in a much higher energy production.
Adaptability to changing conditions: MPPT allows for adaptation to fluctuating solar irradiance and temperature changes to ensure that it maintains energy output even in partial shading and partial cloudiness.
Greater ROI: More energy produced, the better the return on investment, especially for solar systems.
It works as follows
Monitoring : The inverter constantly monitors voltage and current output of the panel.
Algorithm computation: Using the tracked data, the MPPT algorithm calculates the best operating point, known as MPP.
Tuning: The inverter tunes its input impedance to keep the solar panels at the MPP, thereby extracting maximum power.
Key considerations:
MPPT trackers count: Some inverters come with multiple MPPT trackers. This means better optimization of the solar panels depending on the orientation or shading conditions.
Compatibility of the inverter: When selecting an on-grid inverter, make sure that it has the correct MPPT capabilities for your solar panel configuration.
