MPP Solar our job is to promote the use of natural solar energy by providing straightforward solar solutions to installers and distributors. In very simple terms, solar energy creates electricity through silicon atoms’ exposure to sunlight (photons), which causes deficiency and replacement of electrons with the help of a built-in electrostatic field of PN junction made by doped layers of Boron and Phosphate, thus generating electrical current.
We offer two major types of solar energy systems: Off-Grid Solar System vs. Hybrid Solar System, as illustrated below.
While both systems aim to maximize the use of solar energy, their main difference lies in the way they handle storage of energy. In an Off-Grid Solar System, the inverter will attempt to use solar energy for “self-consumption” by sending it directly to load or use it to charge battery. If there’s any excess solar power, nothing will be done as there’s simply no more room for energy storage. Below is a demonstration of the typical Solar First/SBU mode of our Off-Grid Solar Inverters.
On the other hand, a Hybrid Solar System will still attempt to maximize the use of energy through load or charging battery, and any excess power will simply be “fed” to the grid, which act as a nearly limitless power storage. Power feedback to grid can only be done by Hybrid Solar Inverters. This explains explain why the Hybrid Solar System in the diagram above has a bi-directional energy flow arrow to grid. A common misconception where many confuse any system with connection to grid as “grid-tie”, but in fact this is not true. All our Off-Grid Solar inverters have the capability to connect to grid (AC input) but grid is generally used only as a backup power source for load or charging battery.
Our MPI Hybrid series is a very advanced Hybrid Solar Inverter and it has 3 main program modes: Grid-Tie with Backup, Grid-Tie only, and Off-Grid and total 8 sub-modes to accommodate wide range of customer need. For operational concept please see video below.
