RS485-150U Cable)

  • This Cable is used to monitor each controller on the network using Solar Station PC software and update the firmware.


Warm tips:

Step: Connect the system in the order of 1.battery–>2. load–>3.PV array, and disconnect the system in the reverse order 3. 2. 1.

  • NEVER connect the soalr panel array to the controller Without/Before a Battery.
  • Battery must be connected FIRST !!!
  • DO NOT connect any inverter/ wind/Alternator or Charger into the charge controller!
  • If the remote temperature sensor is not connected to the controller,, the default setting for battery charging or discharging temperature is 25 °C without temperature compensation.
  • The wire size is only for reference. If there is a long distance between the PV array and the controller or between the controller and the battery, larger wires can be used to reduce the voltage drop and improve performance.

The Best Ways To Make Use Of The Sun’s Energy

Cutting energy costs and saving the only habitable planet in the universe are both worthy goals. Your electricity bill will only increase in years to come, so it may be a wise choice to start understanding the benefits of solar energy and how it works. In this article we will discuss the basics of solar energy.

There are a couple of different photo-voltaic panels to choose from. Less expensive poly-crystalline panels are not as efficient as the costlier mono-crystalline panels. Find the most practical product so that you can save the most during the year.

When beginning to use solar energy, start small. Purchase a couple solar energy landscape lights. You can find these at most major retailers. Installing these isn’t terribly difficult, you just place them where you want them.

Storage is just as important as the energy that a solar power system produces. Get yourself a battery that can keep large amounts of power stored over time. You may also think about selling any extra energy to the electric company so that you’re able to draw power from them still.

If you decide to lease your solar energy unit instead of buying it, make sure your contract offers you the ability to transfer your lease. This is important because if put your home on the market, you may get stuck with paying for a leased solar energy system that you are not able to use. Having the option to transfer the lease will give the new homeowners a beneficial system, and remove your obligation to pay for it.

Your government may reward you for your solar energy investment. These rebates can reduce your installation costs by almost thirty percent. Contact a local representative or look on the Internet for more information to see what programs are near you.

When putting in solar panels, take a look at the inverter. A green light is normal. If the light blinks or is not on, you have to get a professional. It’s almost impossible for most panel owners to diagnose problems. Support from a qualified technician should covered by your extensive warranty.

Install solar photo-voltaic panels on the roof of your home or just add a solar water heater to save lots of money on the power you use. Solar panels are ideal for locations that receive between 5 and 6 full hours of direct sunlight daily. Solar heating can lower the cost of keeping a pool heated.

If you appreciate the environment, you should consider solar energy. Solar energy is about as green as it gets due to the fact that is uses the sun, which is a completely renewable resource. Making use of this technology will greatly reduce your use of fossil fuels.

Before you begin to install solar panels, you should check out your area’s regulations. There are many areas in which permits will be required. It would be frustrating to install a system and then have to remove it due to not following pertinent regulations.

Don’t work with pushy salespeople. Unfortunately, you’ll run across quite a few of these in the solar panel business. Be firm and tell these pushy sales people that you will decide after you have examined all the facts. Beware of deals that depend on you acting quickly. Pressure can lead to poor decisions.

Making the switch between two types of energy sources is a bit of a challenge, but it is one that could ultimately save you thousands of dollars. Hopefully, what you’ve just read has convinced you of the reasons why you need to take advantage of solar energy. Use what you’ve learned here to go green!
