Overview — Zamp 8 Amp 5-Stage PWM Charge Controller
Used in our 45-watt, 90-Watt Long portable kit, and our solar maintainers, our smallest charge controller is compatible with Lithium, Gel, AGM, Conventional lead-acid (wet) batteries, and LTO 12-volt batteries. It can manage up to 135 watts and 8 amps.
Protects and Regulates
All our charge controllers use pulse width modulation (PWM) and five stages of charging to regulate the flow the electricity to your battery. This protects your battery from overcharging, expands your battery’s lifespan, and keeps your panel safe from backflow electrical currents, among many other protections and benefits.
Indicates and Displays
This weather-resistant charge controller has three LED indicator lights that let you monitor charging status, battery condition, and any system faults.

FAQs — Zamp 8 Amp 5-Stage PWM Charge Controller
Q: Can I connect two charge controllers to the same battery bank (e.g. combine a roof mount system and a portable kit)?
Answer: Yes, two independent charge controllers can be connected directly to the battery as long as both controllers are set to the same battery type.
The charge controllers will not work properly if wired in series, one to the other.
Q: Is the Zamp Solar port reverse polarity?
Answer: No, but they are different from other brands of solar ports because all of our SAE plugs are polarity-protected for safety reasons. That means the positive pin on all of our SAE plugs is set back and covered to prevent accidental contact that could damage your panel, short your battery, or give you a pretty nasty shock. So, because of the polarity protection on our plugs, Zamp Solar ports are only compatible with Zamp Solar SAE plugs.
Q: What does the b01 601 error message on my charge controller mean?
Answer: This common error code means the charge controller can’t see the battery bank. The most common cause of this is a bad connection between the charge controller and the battery bank
Q: Why isn’t my solar system charging my battery?
Answer: When a solar system isn’t working, the most common culprit is a wiring problem. Our troubleshooting document can help you identify the disconnect and get it fixed. If you’re still having issues, please contact us for further assistance.
Q: What batteries should I use?
Answer: Any type of 12-volt deep cycle battery (lithium, gel, AGM, conventional lead-acid (wet), and calcium) will work with your Zamp Solar system. If you choose to go with two 6-volt batteries, make sure that you use two of them wired in series to create a 12-volt battery bank.
Q: What size kit do I need to power my RV?
Answer: Everybody’s needs are different, but we can certainly provide some insight into what size solar kit typically works for various sizes of RVs. Check out our infographic to see which of our kits might work best for you.
Q: I have a Zamp Solar Ready sticker on the side of my RV, what does that mean?
Answer: If an RV is “solar ready,”it means that the RV came pre-wired for our solar products with either a 3-port roof cap, a single port roof cap, or a side-wall port. However, each manufacturer does it slightly differently—some include full wiring, while others only wire from the roof to the batteries.
