Charging NEC Energy Solution Batteries

In response to requests from system designers seeking to leverage NEC Energy Solution’s ALM 12V35 batteries with Morningstar charge controllers, an application note was developed through a collaborative effort between the two companies.  Systems incorporating both ALM 12V35 batteries and Morningstar charge controllers are well suited for a wide range of PV+Storage applications.  The information in the application note serves as a guide to help configure settings based on the particular Morningstar controller that is used.  Performance may vary depending on use conditions and application.  [Read more…]

Remote Monitoring of Off-grid Systems

Being able to remotely monitor PV systems is important to reducing time and costs associated with site visits. This is obviously especially important for off-grid systems, which are often in even harder to reach or remote areas—geological monitoring, mines, telecom, industrial automation and agriculture applications.

Comparing Four Versions of Morningstar 600V Charge Controllers

Morningstar’s TriStar MPPT™ 600V Solar Charge Controllers have proven to be a highly reliable solution to enable several application scenarios including: The use of smaller diameter wire to reduce costs and simplify installation. Long wire runs from the array to the controller. New and retrofit grid-tie systems with battery backup. Each of our 600V charge controller SKU’s are pictured and described below so you can make sure you use the version that is most appropriate to meet your needs. TS-MPPT-60-600V-48  Standard version: smallest version that does not have a PV disconnect or transfer switch. This version is most often used in high voltage off-grid residential and telecommunications applications with long wire runs from the array to the controller. TS-MPPT-60-600V-48-DB DB version: includes a disconnect box to disconnect power from the PV array and connection to batteries.  This version is most often used in off-grid residential and telecommunications applications by those who don’t want to be tasked with installing their own disconnect solution to meet safety requirements. TS-MPPT-60-600V-48-DB-TR TR version: includes a transfer switch which directs PV array power to a grid tied string inverter or to a battery bank. This version is used to retrofit grid-tied systems with battery backup for critical loads. TS-MPPT-60-600V-48-DB-TR-GFPD TR with GFPD version: includes a transfer switch and a pre-wired connection to a ground fault protection device. This version is used to retrofit grid-tied systems with battery backup and it meets US NEC requirements for ground fault protection.  

5 Reasons Why Customers Prefer Morningstar’s EMC-1

Morningstar’s new Ethernet MeterBus Converter (EMC-1) enables IP-based network and internet connectivity to compatible Morningstar products for remote monitoring and configuration of system settings. Here are the top 5 advantages of the EMC-1 versus other serial converters on the market: 1. Wide operating temperature range from -40°C to +60°C and conformal coating designed for the harshest off-grid environments. 2. Wide operating voltage range allowing a single product to be compatible with 12, 24, and 48 volt battery systems. 3. Auto-detection and configuration when connected to compatible Morningstar products. 4. Low power consumption (2W maximum). 5. Simple connectivity via an RJ-11 port.

15,000 New Modules Added To Morningstar’s String Calculator

Morningstar has recently updated its online String Calculator.  This powerful tool can assist you with proper sizing of the solar array for all of our MPPT and PWM solar controller models.  Our recent update adds over 15,000 new solar modules including many of the newer 300W+ models.  These 72 cell modules are perfect for use with any Morningstar MPPT controller or PWM solar controller that supports 24V batteries. The String Calculator provides a quick and easy way to determine the number of solar modules that can be configured in series and parallel based on battery, controller and temperature conditions associated with your system.  The underlying database of module specifications is professionally managed and updated by the manufacturers themselves, ensuring a complete and accurate listing for the global market.  In the off-chance that your particular module is not in our database, you can also choose to manually enter module specifications.  To view a short video that will help you learn about how to best use the string calculator, click here.
