Best answer


The SunSaver MPPT supports the industry standard MODBUSapplication protocol via itsMeter RJ-11 interface. A Meterbus to Serial Converter(MSC) is required to adapt the Meter interface to an isolated RS-232 interface**. This document assumes the user is familiar with the MODBUSprotocol and its terminology.

  • Why sunsaver MPPT鈩?with Trakstar technology?

  • The SunSaver MPPT鈩?with TrakStar technology is the perfect charging solution for smaller off-grid solar systems up to 400Wp. An industrial-grade design proven in challenging applications and environments, SunSaver has been called the single most successful charge controller in the solar industry.

  • Which ProStar MPPTs can be used with a meterhub?

  • In such a system, the ProStar MPPT, ProStar Gen 3, SunSaver Duo, SunSaver MPPT, and SureSine, which do not have a standard RS-232 connection, can be used with a MeterHub. Figure 40 below illustrates how to establish a multiple device connection over RS-232 via a Morningstar MSC PC MeterBusTMAdapter with a MeterHub.

  • Why sunsaver charge controllers?

  • An industrial-grade design proven in challenging applications and environments, SunSaver has been called the single most successful charge controller in the solar industry. Maximum power point tracking (MPPT) optimally matches the solar array to the battery鈥攏o wasted PV electricity. enables use of high voltage modules for off-grid battery charging.

  • Does the TriStar MPPT support read and write Modbus鈩?requests?

  • All incoming requests addressed to controllers and devices that are connected (bridged) to the EIA-485 port on the TriStar MPPT will be passed both READ and WRITE MODBUS鈩?requests without exception. Setting switch #8 on the TriStar MPPT only prevents WRITE requests to the local controller.
