Many artificially powered charging systems are programmable, but usually the choices are minimal. Not all solar charge controllers are designed to have an easy way for the user to put the batteries in a Bulk charging stage at any time of day other than dawn. Solar charge controllers operate 24/7, and they rely on an internal algorithm to determine when it is morning and time to start the Bulk charging stage. This gives you a way to force the batteries into the Bulk stage and start the charging process from scratch. Most systems will test the battery voltage to see if they should jump into the Bulk stage as soon as they are turned on. Therefore, solar charge controllers have a lot of extra complexity built into their charging algorithms so they can handle the situations where, for whatever reason (lack of sun and/or too much demand from the appliances in the RV or boat) they aren’t actually charging the batteries but are just slowing down the discharge rate!Ībility to Restart the Charging Process with the Bulk StageĪrtificially powered charging systems can all be turned on or off with the flick of a switch. In fact, if the current draw is big enough, not only will the solar charge controller fail to keep up with the sudden demand, but the net effect on the batteries may be that they are temporarily being discharged a little bit rather than charged. However, solar charge controllers may or may not be able to meet the challenge, depending on the time of day and amount of cloud cover. In contrast, “naturally powered” chargers may or may not be able to deliver their maximum rated current when called upon to do so. The biggest difference between these two types of charging systems is that artificially powered charging systems - converters, inverter/chargers and alternators - can all deliver the maximum amount of current they are rated for as soon as they are turned on. Note: Although this series doesn’t discuss wind charging systems, the same principles apply.Ībility to Deliver the Maximum Rated Current There are two basic types of multi-stage chargers for RVs and boats: those that are “artificially powered,” either by electricity, by an engine or by a generator, and those that are “naturally powered” by the sun (or wind). “ARTIFICIALLY POWERED” versus “NATURALLY POWERED” CHARGING SYSTEMS Sizing an Engine Alternator to a Battery Bank.What Values Do You Program into a Charging System?.“Artificially Powered” versus “Naturally Powered” Charging Systems.
