The 490 Watt RV Solar kit is Powerful, Reliable and Dependable. Easy to install with only two panels to install and connect on an RV or Off Grid 12v-24v system. This kit utilizes “oversizing” by using higher voltage panels. You can size Morningstar’s MPPT controllers well above the Maximum Nominal Solar PV Input rating without damaging the controller and without the charging current exceeding the maximum output current rating.
Energy harvesting during lower power production periods (cloudy weather) is often more valued than during times when the array can operate at full power (sunny weather). These controllers can limit current and will run at 100% of rated output.
Oversizing runs the controller at maximum levels more consistently
The controller was designed with this power-shaving capability and when oversized it does not void the warranty.

The 40a Morningstar MPPT charge controller out performs all other comparable controllers. MPPT TrakStar adds 10-30% Gain in charging early, late (low light conditions) and especially in colder weather
Morningstar’s Prostar MPPT solar controller with TrakStar Technology™ is an advanced maximum power point tracking battery charger for off-grid solar systems.
The controller features a smart tracking algorithm that maximizes the energy harvest

Add Optional RECOMMENDED TEMPERATURE SENSOR.
It sends more voltage when batteries are cold so they still 100% charged.
It sends less voltage when batteries are hot so they don’t overcharge.
kit does not include the 2 battery cables that go from controller to battery posts. Keep them short with controller mounted as close to battery bank as possible.
12v Inline fuses and breakers are very inexpensive and easy to find locally at auto parts or car stereo stores
