Product information

The Morningstar SureSine 300W pure sine wave inverter is designed to meet the needs of rural PV electrification requiring AC power for solar home systems, schools, community centers and health clinics. This inverter is also a good choice for small PV systems for telecom, remote cabins, weekend homes, RV/caravans and boats. It has outstanding surge capability for a small inverter. The SureSine handles a 200% surge during load start-up, to a maximum of 600 watts.

The SureSine uses epoxy encapsulation, conformal coating, stainless steel hardware, and an anodized aluminum enclosure to protect against harsh tropical and marine environments. AC output connection does not have an AC receptacle so it needs to be hardwired. 2-year warranty.

Wave quality: Pure Sine Wave
Rated capacity: 300 Watts
AC Output: 115 volts / 60 Hz

Sizing guide

Quick guide for selecting the right charge controller

Each time you charge deep cycle batteries with solar panels, it's necessary to use a charge controller in the circuit to protect the battery from over charging, and in some instances from over discharging. The only exception is when using solar panels smaller than 5W. Choosing the most suitable charge controller is simple and only requires two steps:

Step 1 - Voltage selection
Select a charge controller that is compatible with the system voltage. The standard configurations are 12, 24, and 48 volts. If you are wiring your batteries for 24 volts you need a charge controller that is rated at 24 volts.

Some controllers are voltage specific, meaning that the voltage cannot be changed or substituted. Other more sophisticated controllers include a voltage auto-detect feature, which allows it to be used with different voltage settings.

Step 2 - Current capacity

Select a charge controller that can handle the maximum output current of the solar panel (or solar array). The maximum possible current that a PV panel can generate is the “short circuit current,” indicated as Isc in the panel’s label or specs sheet.

It’s recommended to include a safety factor for isolated events as well. For example, a solar panel with a Isc of 7.89 amp could potentially produce an extra 25% on a sunny day with very clear snow pack. (additional light reflected off the snow). This results in a possible maximum of 9.86 amp (7.89 x 1.25 = 9.86 amp). In this case, a 10 amp charge controller would be recommended.

Below you will find a quick guide to choosing the proper charge controller for several popular solar panel sizes.
