How To Maximize the Off-Grid & Hybrid Solar Systems Capacity

Description

Maximize the energy harvesting from the Sun

This course starts by explaining how to maximize the PV energy harvesting from the Sun without electronic components overheating. The course explains what is a Solar Charge Maximizing Controller & its System, the principle of Solar Charge Maximizing Controller, the difference between the MPPT solar charge controller and Solar Charge Maximizing Controller (SCMC), and how the Solar Charge Maximizing Controller is working with MPPT solar charge controller to increase the current capacity of a MPPT solar charge controller system by 2~5 times.

The Benefit and Application of Solar Charge Maximizing Controller System
This course explains the unique benefit of Solar Charge Maximizing Controller System, and why it is most suitable for any off-grid or hybrid Solar PV systems (behind-the-meter _BTM PV power systems) with battery banks.

The course explains that the most important benefit of the SCMC system is that the SCMC system can power any DC load directly without consuming Lithium Iron Phosphate Battery's charging cycles, as the LFP battery in the SCMC system is mainly to maintain the system voltage. And the LFP batteries are not necessarily to be charged or discharged, so its service life will be extended.

The SCMC system may also form a grid-tie hybrid system. The main advantage is that such a hybrid grid-tie system can have all its solar panels functioning to power the local load during a grid power outage.

Common negative and common positive Solar Charge Maximizing Controller (SCMC) system
This course explains what is a common negative & common positive MPPT solar charge controller, and why they must match the same common negative or common positive SCMC design to charge the same battery or battery banks. The course also introduces the method to determine if a MPPT solar charge controller is of common negative or common positive design.

Split-bolt wire(S)
This course explains what is split-bolt wire or wires in a solar charge maximizing controller system. The course explains how the split-bolt connector can be formed, why the split-bolt wire(s) shall be connected to and controlled by the solar charge maximizing controller.

Solar array grounding options
This course explores the solar array grounding options in a Solar Charge Maximizing Controller System, and further explains why the solar array could be a floating array, or a grounded array, but the split-wire(s) must never be connected to the ground in a solar charge maximizing controller system.

Types of solar energy storage battery and SCMC system battery capacity sizing guidelines
This course studies the charging and discharging behaviours of several common types of solar PV energy storage batteries. The course explains the construction details and State-of-Charge of Lithium Iron Phosphate batteries, and why it is used in the SCMC system to maintain the system voltage.

The course explores the application of lead / acid based batteries in the SCMC system, and how it may be integrated in the SCMC system with LFP batteries.

This course also introduces the system sizing and battery sizing guidelines for the hybrid grid-tie system when the grid-tie approval is obtained.

Types of solar power cable and wire gauge sizing
This course introduces the common types of solar cables used for connection between solar PV panels and combiner boxes. The course provides the voltage drop guidelines for solar cable gauge sizing, and the online tool for solar cable sizing.

Locating the major components of SCMC system
This course explains where the LFP batteries and other major components, such as inverters, MPPT solar charge controllers, automatic transfer switch shall be located for the safe and efficient operation of the SCMC system.

Common electrical components used in the solar charge maximizing controller system

This course introduces following components that are commonly used in the SCMC systems: DC disconnects, DC breakers, solar wire connectors, split bolts, power distribution blocks, wire lugs, terminal blocks, Anderson quick disconnects, solar cable glands, combiner box, junction boxes, electrical enclosures.

Video demonstration of solar cables MC4 & split-bolt connection forming techniques
