Download the White Paper: Solar Controller Integration with AC Rectifiers

General Editor — Tue, 07 Dec 2021 20:45:20 +0000

Please click here to download the Solar Controller Integration with AC Rectifiers white paper. For over 25 years Morningstar solar controllers have been incorporated into off-grid and backup grid-tied systems. Many of these systems include a rectifier to charge a battery from an AC power source. This power source can be the utility grid or a generator. This paper will show how a solar PV system can be integrated into these types of rectifier systems. Read the white paper to learn:

About the benefits of adding solar to AC rectifier systems including UPS backup and off-grid generator systems
How to prioritize solar energy over AC rectifier systems to reduce the levelized cost of energy (LCOE)
How to provide more reliable backup power for longer outages
How to reduce generator run time and battery cycling
About multi-stage charging control
Coordinating the solar charge controller with the rectifier

Download the White Paper: Higher Voltage PERC and Half-Cell Solar PV Modules

Matt Lee — Thu, 25 Feb 2021 17:20:00 +0000

Please click here to download the Higher Voltage PERC and Half-Cell Solar PV Modules white paper. Over the years, PV modules have continuously improved and become more efficient and less expensive. The introduction of new PERC PV and half-cell technology has not only affected efficiency and cost, but it has also increased the voltage ratings of PV modules. This paper will discuss how these new higher voltage PERC modules affect string sizing when used with Morningstar controllers. Read the white paper to learn

How new PERC Half-Cell modules can provide more power to your off-grid systems
Why the increase in MPPT boost associated with PERC Half-Cell modules over traditional 36 and 72 cell modules, makes MPPT controllers more economically viable than ever
How MPPT controllers in hot climates can still provide significant power boost, when used with new PERC Half-Cell modules
How new PERC Half-Cell modules can perform better under partial shading conditions
Why PWM controllers are often unsuitable with 60 cell modules—even the higher voltage PERC modules
How Morningstar’s string calculator can help you determine optimal and problematic array configurations when using PERC Half-Cell modules

Download the White Paper: Sizing Benefits of MPPT Controllers with Nominal Voltage Arrays

Matt Lee — Thu, 29 Nov 2018 21:25:29 +0000

Please click here to download the Traditional PWM vs Morningstar’s TrakStar MPPT Technology white paper. Morningstar’s MPPT charge controllers use the TrakStar advanced control MPPT algorithm to harvest maximum power from a Solar Array’s peak power point. It is generally accepted that even the most basic MPPT controller will provide an additional 10‐15% of charging capability, when compared to a standard PWM regulator. Besides this extra charge capability, there are several other important differences and advantages between PWM & MPPT technologies—these basic differences & advantages are outlined in this whitepaper. This paper explains how to provide a battery backup PV solutions that is:

cost-effective
easy to implement for new and existing systems
capable of highly efficient battery charging

Download the White Paper: Parallel Charging Using Multiple Controllers With Separate PV Arrays

Matt Lee — Tue, 27 Nov 2018 17:06:24 +0000

Please click here to download the Advantages of Morningstar’s Parallel Charging Using Multiple Controllers With Separate PV Arrays white paper. Large off-grid and battery backup PV systems, often require greater charging than a single controller can provide. To meet the charging requirements of these large systems, several TriStar or TriStar MPPT controllers can be connected in parallel to a battery bank. Each controller is connected to its own separate PV array. This document provides answers to frequently asked questions, and tips concerning the operation and setup of these large multiple TriStar and TriStar MPPT controller systems.

Matt Lee — Tue, 27 Nov 2018 01:53:45 +0000

Please click here to download the Sizing Benefits of MPPT Controllers with Nominal Voltage Arrays white paper. The tracking capabilities of many MPPT controllers require a voltage input window that must be significantly higher than battery voltage. Morningstar’s MPPT controllers, on the other hand, are engineered to impose no such limitation, and in many cases, we encourage these configurations for the optimal performance and cost benefits.
