About Solar Regulators

 

If you have 800 watts in solar panels, you want to get 800 watts out of them.

Simple charge controllers can't do that.

800 watts at 20 volts on your solar panels is 40 amps which is fine.

But when your 20 volt solar panel voltage is pulled down to 12 volts by your batteries you only get 12 volts x 40 amps = 480 watts.

MPPT charge controllers convert power.

800 watts at 12 volts is 66 amps and that's what you get, or close to it at say 90% system efficiency, which is 60 amps.

You have 40 amps from your solar panels and that is converted to 60 amps going to your batteries by power conversion. 

40 amps or 60 amps into your batteries. Which would you prefer ?

 

 

TriStar TS-MPPT-45 and TS-MPPT-60

Solar Controller with Maximum Power Point Tracking

shown with TS-M-2 panel meter

Morningstar’s TriStar MPPT solar controller with TrakStar Technology™ is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems up to 3kW. The controller provides the industry’s highest peak efficiency of 99% and significantly less power loss compared to other MPPT controllers.

The TriStar MPPT features a smart tracking algorithm that maximizes the energy harvest from the PV by rapidly finding the solar array peak power point with extremely fast sweeping of the entire I-V curve. This product is the first PV controller to include on-board Ethernet for a fully web-enabled interface and includes up to 200 days of data logging.

Maximizes Energy Harvest
