Titan Generator Questions

Yes. Pretty much with any solar generator system out there that I’m aware of you can use it while it’s being charged.

No. You can use any solar panels you’d like. There are two solar input ports on the Titan. Each one is rated to 145v and 30a. As long as your panels do not exceed those parameters you will charge just fine. Each port will only let 1,000w pass through it. The Titan comes with an PV Connector adapter so as long as the solar panels have PV Connector connectors they should be fine.

Yes. As long as you don’t exceed 145v and 30a. As an example, if port 1 had 1,500w of solar panels attached to it and the panels were making more than 1,000w from the sun, only 1,000w will go through the port. Each port can have more than 1,000w in panels but the Titan limits each port to only let in a max of 1,000w per port.

Yes. The Titan is the first of its kind to have a stackable battery design. Each battery has a 2,000wh capacity that can be sandwiched between the original battery and the inverter. Or it is possible to remove the plug covers from the bottom of the original battery and simply add the new battery below the original battery.

No. You can use any type of external battery. It is recommended to use a lithium base since the Titan battery is Lithium NMC. The Battle Born 24v battery is a great match for the Titan. Or two Battle Born 12v batteries can be paired together in series to make 24v to attach to the Titan. Make sure the external batteries are within .1volts charge of the Titan battery.

First of all, no one has done as much research and testing as I have when it comes to each component of the kits. Many people use cheap quality flexible panels that look similar to the Flexx 100 panels but do not come close to the same amount of power production. Second, I have been working on the Titan with the manufacturer almost since its inception. I have had first-hand experience with it when NO ONE else has.

Yes, they are IP65 waterproof which means they can handle heavy rain no problem.

Yes. The solar generator is essentially a computer. It has microchips, diodes, resistors and so on inside that will fail to work after an EMP. The Titan Solar Kits come with faraday bags to help protect against EMP attacks.

Yes. Since the Titan uses a Lithium-Ion battery it needs to be protected. Lithium-Ion batteries have micro-inverters in them that can be damaged from an EMP attack.

No. If there is an opening in the faraday/emp bag then it does not work. Also if there were cables sticking out of the bag, the cables would act as an antenna and would guide the EMP into the bag.

Yes. All that is needed is the proper Anderson SB50 connection cable and the batteries can be strung along however preferred. Be sure to use 6 AWG cables since that’s the thickest the SB50 connector can fit.

Yes. Simply ensure that if using something like a wind turbine that it is a 24v setup not a 12v. It can charge from an AC charger while charging from solar panels while being run.

No. Since a car’s alternator makes 12v power and the Titan uses 24v power, the alternator cannot be used for charging. One option is to have a 12v 750w or 1,500w inverter installed in the car and use the 1 AC wall charger for the 750w inverter or 2 AC wall chargers for the 1,500w inverter.

General Solar Panel Questions

ETFE stands for Ethylene-Tetra-Fluoro-Ethylene. It is a type of high-strength fluorine polymer that is used as the finishing layer on the solar cells. It is corrosion, stain, and discoloring resistant making it the most ideal finish on solar panels, especially flexible solar panels. ETFE finish will generally last 20+ years and retain 80% or more of its original efficiency, clarity and quality. It is always preferable to PET finish. More often than not you can easily spot ETFE because of its matte low gloss finish. The Flexx 100 solar panels use an ETFE finish.

PET stands for Polyethylene terephalate. Commonly used on solar panels it is a plastic that helps protect the solar cells from damage. PET is also used as water bottle plastic, or even disposable household cleaner bottles. PET works well for short periods of time but will not stand the test of time like the ETFE finish will. PET is often noticeable by its high gloss look. PET will often flake, discolor or crack within 6 to 12 months of continual use in outdoor conditions. Much more cost-effective in the short run but will not last in the long run.

Yes, it is only a protective plastic covering which helps the panels keep safe from scratches in shipping. The plastic covering is not UV proof and if left on will eventually adhere to the solar panel causing power loss.

No. As long as the panels are not connected to the generator when the EMP happens they will not be damaged.

Monocrystalline solar panels are panels that have their solar cells cut from one large piece of silicon. Mono panels have a higher efficiency rating and cost more than Polycrystalline cells.

Polycrystalline solar panels are panels that have their solar cells molded from lots of fragmented pieces of silicon. Poly panels have a lower efficiency than mono panels but cost less than monocrystalline cells.

Solar panel efficiency refers to how much light is converted into power per cell. The more efficient a panel is the fewer cells it will need to make the same amount of power as a solar panel that is less efficient. More than anything efficiency means more power with less space.

Standard Testing Condition is the environment in which solar panels are tested. This standard is used worldwide and helps give a benchmark for different companies to work off of so customers can compare panels. These are perfect conditions and the parameters are: 77 degrees Fahrenheit, Solar Irradiance 1000watts/sqm (sun at noon position in the sky), and Atmospheric density of 1.5 (90 degrees perpendicular to the solar panel at 500ft above sea level).

Normal Operating Cell Temperature is the environment in which solar panels are more commonly found. This is a rating according to the manufacturer that will tell customers how much power they should actually expect to be close to when using that solar panel. The conditions are: 113 degrees Fahrenheit, Solar Irradiance 800w/sqm (sun just outside of peak hours), Atmospheric Density of 1.5 with 85-90% of STC.

Pmax stands for the maximum power point for the solar panel. It’s the maximum power that can be produced by the solar panel. The maximum amount of volts and amps combined to make the max amount of watts.

Vpmax is the greatest voltage of the solar panel.

 Ipmax is the greatest amperage of the solar panel.

Voc stands for Open Circuit Voltage. This is how many volts the solar panel can make when there is no load on it in standard testing conditions.

Isc stands for Short Circuit Current. This is the highest amount of amps the panel can produce under standard testing conditions.

Charge Controller Questions

Pulse Width Module is a type of charge controller. It is a simple computer that helps control how much power is made from the solar panels. PWM charge controllers are very affordable, small and lightweight. They will not help the solar panels make more power as an MPPT charge controller will. In almost every case, it is best to go with an MPPT charge controller instead.

Maximum Power Point Tracking is a type of charge controller. It is a computer that helps the solar panels make more power especially when there are not ideal solar conditions. The MPPT costs more, weighs more and is larger than an equivalent PWM charge controller. It is almost always recommended to go with an MPPT charge controller because it will help make much more power from solar panels than a PWM.

IP-Rating Questions

IP65 stands for the protection level the junction box has on a solar panel. IP65 means that it is dustproof and waterproof against low-pressure jets. See the image below

 IP67 stands for the protection level of the junction box has on a solar panel. IP67 means that it is dustproof and waterproof against submersion at 3ft for 30mins. See the image below

General Solar Questions

Volts x Amps = Watts. For example, a laptop that uses 120 watts and .5 amps would use 60 watts. (120 x .5 = 60) That means in the course of 1 hour it will have consumed 60 watts of energy.

Direct current means that the electricity being used does not need to be converted to AC (alternating current) in order to run the device that is connected. DC power is more efficient meaning it uses less overall power when compared to AC power. Common items that use DC power are RV fridges, tire pumps, phone charging adapters, camping lights etc… DC requires no inverter as long as the device being used is designed for DC power.

Alternating current is more common than DC (direct current) power. AC power has to be converted from DC power. This conversion means that there is a power loss, but the loss is fairly minimal. More common for running items around the house. AC power requires and inverter to convert the power from DC to AC.

Nominal voltage is a way of defining a voltage class. For example, a 12v battery will rarely be exactly 12v. Depending on the type of battery chemical the voltage range can be anywhere from 10.8v to 14.4v. That means anywhere in the voltage range the battery will operate, but, at lower voltages, the battery generally doesn’t work as well.

No. As long as the panels are not connected to the generator when the EMP happens they will not be damaged.

Peak solar hours are how many hours per day that solar panels can make their full power. Generally, 5 hours is the rule of thumb for the USA. This varies depending on the time of year greatly as well as living in the north or south of the country.
