![]() ![]() If a panel puts out 2 watts or less for each 50 battery amp-hours, you probably don’t need a charge controller. You don’t need a charge controller with small 1 to 5 watt panels that you might use to charge a mobile device or to power a single light. Charge controllers prevent this from happening by acting as a valve.ĭO YOU ALWAYS NEED A SOLAR CHARGE CONTROLLER? This can cause a slight discharge from the battery. ![]() At night, panels may naturally pass some of that current in the reverse direction. This will prevent an over-discharge.īlock Reverse Currents: Solar panels pump current through your battery in one direction. It will automatically reconnect to the battery when it is being charged. ![]() Low voltage disconnects: This works as an automatic disconnect of non-critical loads from the battery when the voltage falls below a defined threshold. In larger systems, we also recommend a double safety protection with circuit breakers or fuses. Charge controllers prevent these overloads from occurring. This can lead to overheating or even fires. If the current flowing into your batteries is much higher than what the circuit can deal with, your system may overload. Overload protection: Charge controllers provide the important function of overload protection. Overcharging batteries can be particularly damaging to the battery itself so charge controllers are especially crucial.Ĭharge controllers also offer some other important functions, including overload protection, low voltage disconnects, and blockage of reverse currents. Regarding “what does a solar charge controller do”, most charge controllers has a charge current passing through a semiconductor which acts like a valve a to control the current. Charge controllers also prevent your batteries from being overcharged by reducing the flow of energy to the battery once it reaches a specific voltage. This helps preserve the life and health of the batteries. They also prevent battery drainage by shutting down the system if stored power falls below 50 percent capacity and charge the batteries at the correct voltage level. Charge controllers prevent your batteries from being overcharged by limiting the amount and rate of charge to your batteries. The charge controller in your solar installation sits between the energy source (solar panels) and storage (batteries). They protect your battery storage components, and they ensure everything runs efficiently and safely throughout the lifespan of your system. Solar charge controllers are a critical component in every solar installation. I would recommend K40 Whisper in any case and hope to see some added functionality down the road.Authors Note: This has been updated on with updated information, links, and resources. I had troubles with CorelDraw 12 part of CorelLASER on Win 10 and gave up on it. The software runs fine on the latest Windows 10 and my old XP Pro system. Most likely my Visio doesn’t follow the current standard (typical Microsoft).ĥ. svg file is missing something that a Inkscape.svg file adds. svg file is first imported or opened in Inkscape then re-saved. These can be sent to Whisper if the Visio. I’ve used MS Visio 2003 for years for quick 2D engineering sketches. With the CorelLASER extension speeds over were wonky.Ģ The Halftone raster engraving is very good and for my purposes makes the change to whisper well worth it.ģ.Inkscape, once you get use to a few non-intuitive methods (trim), is good and must be loaded on the computer.Ĥ. Other than it’s easier and cleaner than CorelLASER, there are a few outstanding differences.ġ.The cutting speeds are more true with K40 Whisper. I’ve been using the Inkscape/K40 Whisper duo for a few weeks or so and it is a quantum leap from the delivered SW. ![]()
