Knowledge Base Article for Zamp Solar ZS-30A Charge Controller The Zamp Solar 30 Amp 5 Stage Digital Deluxe Solar Charge Controller # ZS-30A has PWM or Pulse Width Modulation, which is a digital signal that is used to control power applications and has 5 stages of charging for best battery health and longevity. This controller can support and is programmable for the 4 typical types of deep cycle batteries – WET, GEL, AGM and Calcium. We pre-set the controller at the factory according to what batteries are installed. 12 volt solar charging power. LCD screen displays battery voltage, charging current, charging capacity, battery types and faulty codes. LED light indicators show charging status and battery condition. 5 stages of charging: Level 1 – Soft Charge – When batteries suffer an over-discharge, the controller will softly ramp the battery voltage up to 10V. Level 2 – Bulk Charge – Maximum current until batteries rise to Absorption Level. Level 3 – Absorption Charge – Constant voltage charging (battery is over 85%). This stage takes longer than any other stage to complete. You will typically see your battery status remain in this stage unless you are not using the camper. The full battery indicator is about the last 2% and while running lights and other components it will remain in the absorption stage. *Battery volts displayed during this stage are charging volts not actual battery volts. Level 4 – Equalization Charge – Only for WET battery or Calcium battery type. When the battery is deeply drained below 10V, it will automatically run this stage to bring the internal cells to equal states and fully complement the loss of capacity. (Gel and AGM batteries do not run Equalization Charge). Level 5 – Float Charge – Battery is fully charged and maintained at a safe level. Fully charge is more than 13.6V. Includes a port for an optional external battery temperature sensor. Zamp Charge Controller & Digital Monitoring System (Battery Volts) Both systems will display charging volts rather than actual battery volts when power is being supplied to the batteries. Customer interaction The charge controller has 2 buttons. One button labeled Amp/Volts can be used to scroll through relevant information Amp/Volt Button Current battery volts or charging volts Current Amps being supplied to the battery (Initial startup will be lower amps and slowly increase to maximum output depending on sunlight available. Current total of Amp Hours supplied within the 24 hour timeframe. This setting will reset with every 24 hour period. Current Battery Temperature. (Displayed in Celsius). This is used by the charge controller to monitor the battery. Battery Type Button This is pre-set at the factory based on the type of batteries installed and should only be changed if you replace your batteries with a different battery type. Zamp Error Codes: P01 - Solar Panel Reverse Connection P02 - Solar Panel Over Voltage 601 - Battery Disconnected or less than 3.0 Volts 602 - Battery Reverse Connection 603 - Battery Over Voltage (> 17.5 Volts) 604 - Battery Temperature over 65C

What is Galvanic Reaction? - When two dissimilar metals are in contact and exposed to an electrolyte substance it causes one of the metals to lose ions and slowly consumes that metal. - It works much like a battery. One of the metals will become and act like an Anode(Negative) and the other a Cathode(Positive). This process will slowly consume the Anode and actually strengthen the Cathode. - Galvanic reaction occurs when an electrolyte combines with water. Depending on which electrolyte is present, it will completely(strong) or partially (weak) ionize with the water to form a strong or weak electrolyte substance. What is an electrolyte substance? Strong Acids Examples: Hydrochloric Acid, Sulfuric Acid, and other Acids Strong Bases Examples: Sodium Hydroxide, Calcium Hydroxide, and other Hydroxides. Salts Sodium Chloride Winter Road Treatment: - Different cities utilize a handful of different chemicals to treat roadways for ice. Most of these are from a form of chloride which does become an electrolyte once dissolved with water. TIP: It is always a good idea to clean these chemicals from any vehicle and/or camper when possible. What type of impact does this play on Aluminum? - When oxygen is present (in water), aluminum naturally reacts to form aluminum oxide and this is the key to its ability to resist corrosion. Unless exposed to a substance or condition in which destroys the protective layer, aluminum will remain resistant to corrosion. - When aluminum contacts another metal(steel for example), it sets in place the possibility of a galvanic reaction if an electrolyte substance comes in contact with the metals. What does Oliver do to prevent this natural process? A protective layer, cavity spray, is placed between the two metals. Zinc anodes are attached to the aluminum frame The Zinc becomes the anode part of the equation and if the galvanic reaction process takes place, it will consume the Zinc anode instead of the aluminum frame. How often should I check my Anodes? - Depending on where you live or where you travel you may or may not even have a galvanic reaction but it is still a good idea to inspect your anodes at least once a year and more if you start to notice that the anode is deteriorating.

Issue: A/C Fan runs when mode set to furnace Models Impacted: Dometic Penguin II equipped Information: The on-board thermostat communicates with the Dometic Penguin II A/C unit and the A/C unit then communicates with the Furnace. When the mode is set to Furnace the A/C fan should not run if set to AUTO. If the fan speed is set to LOW or HIGH, this will cause the A/C unit fan to run with the Furnace as a means to distribute the inside air flow. If you are experiencing this issue, please ensure that the fan speed on the A/C is set to AUTO. Resolution: Normal Operation *If the A/C fan runs when set to Auto and mode is set to Furnace, then another issue exists and the Dometic A/C unit should be inspected by a Dometic certified technician.

I wanted to let everyone know that we are working with a rubber manufacturer and having them perform test for us, as we do not have the means to do this internally. We want to make sure that we resolve the black streak issue but not at the expense of creating a new problem. The concern with the white neoprene gaskets is that they will yellow over time especially if it is not rated for exterior use. We also have to make sure that it is rated at an IP66 rating and ensure that it won't leak. The quickest and easiest method would be to put some type of clearcoat protection over the gasket but how long will this last and how often would it have to be re-applied. We want to do our due diligence to find the best solution for our customers and not just a quick fix that might create other issues.

I wanted to let everyone know that I have posted in the Technical Service Bulletins area in regards to the black streaks issue. I will be posting in this new section as I become aware of any new issues and updating as I get new information. I would also like to thank all of our customers for helping me with new issues as they arise and would like to continue getting feedback from everyone.

Issue: Black streaks running down side of camper due to porch light gaskets. Models Impacted: 2016 - 2017 Models Information: At this time the manufacturer of the porch lights has no intentions of replacing and/or designing a different gasket to resolve this issue. Oliver is researching and testing some different gasket materials to find a long term solution for our customers. We are aware of some different methods being used by our customers to resolve this issue, ie: Murphy's Oil and DAP silicone. Resolution: Currently in Research & Testing *This thread will be updated as new information becomes available.

Hello Everyone, I have gotten several calls in regards to the axle size and capacity so I thought I would stop by say hello and make an official statement. Hope everyone is enjoying their Oliver camper and travels. The Legacy Elite 18.5' comes with a 5200lb 12x2 axle that is derated to 5000lbs because of a spring measurement that is 3/4" outside the norm for a 5200lb axle. This is the reason why the GVWR for the Legacy Elite is listed at 5,000 lbs. This axle does have the 12" brakes and 6 lug. The Legacy Elite II is currently being built with dual 3500lb. 10 x 2.25 axles putting the GVWR at 7,000 lbs. The brakes are 10"brakes and 6 lug. Some of the earlier model Elite II trailers were built with the 5200 lb. axles as well as a few models that were produced during November 2014- December 2014. This short run was because Dexter had derated it's 3500lb axle that we were using for the Elite II. We immediately ordered the 5200lb axles during that short run because we chose not to use the derated axles and only switched back to the 3500lb axle once we could get it without it being derated. The website is incorrect where it states 12" brakes on the Elite II page and I will make sure that this gets resolved. With dual axles and 4 brakes it isn't necessary to have the 12" brakes. - Hope this helps, but if anyone has any questions, please feel free to give me a call. - Jason

This is a great question and one that many of our customers have started to ask. To access the plumbing under the bathroom sink you would need to cut away the caulk from around the vanity. Once the caulk has been removed you should be able to pull the vanity out. *CAUTION - DO NOT try to pull it out with the caulk still in place. We use 3M 4000 caulk which is a semi-permanent caulk and it will rip the gelcoat if it isn't cut before removal.

Hello everyone! Rally time is getting closer. We have about 13 trailers that can be here for our 1st Oliver Rally. This Rally was put in place with very short notice and I know that many are unable to attend due to other pre-planned arrangements. Hopefully we will get another Rally on the books sometime next year and have at least 6 moths planning so more people can make it back to Tennessee. We will have some people joining us for the rally that are not currently Oliver owners but are interested in seeing the Ollie in person. I wanted to let everyone know that we will be providing your meal Friday night. It will be sandwiches and finger foods. We will be getting together there at NACO at their Town Hall for a meet & greet and food. We will also be in Town Hall Saturday morning for a Pot-Luck breakfast and ask everyone who can to prepare your favorite breakfast food to share with others. NACO has some great activities planned as well for that weekend so those of you who enjoy football can take part in their Football Fanatics party during that weekend. We will also be doing a drawing Friday night for some free giveaways. Our 2017 Inventory Demo will also be on display that weekend for everyone who would like to walk through. We have added as many options to the unit as possible so you can see what each option looks like on the trailer and how it operates.

As try2relax stated, this change will not improve water pressure in any significant amount. However, we have changed our diverter tee out for one that allows for greater flow thru and during testing found that it did help increase water pressure. This change was also implemented in the 2017 model. I haven't heard of many customers having a water pressure issue but we continue to review our processes and continue testing to always see if there is a better way because we want to make sure that our customers get the best. I would like to hear if anyone has experienced any issues with water pressure.

We have modified our plumbing system for the 2017 models by eliminating our 90 degree elbows eliminating potential water leaks. We haven't had any issues with water leaks but we are always looking at how we can make the Oliver better. We are now using pex bend supports. We have also started using a different diverter tee which allows for greater flow.
