Already have a Zamp-ready RV? The Zamp 170W portable kit plugs directly into your existing port without modifications. While the wattage seems low, the weatherproof controller accepts expansion panels up to 510W total when you’re ready for permanent roof mounting.
Installation Safety & Critical Mistakes
Solar fires happen. Usually from poor connections.
MC4 connectors require proper crimping tools—pliers create high-resistance joints that generate dangerous heat. A quality crimping tool costs $30 and prevents potential RV fires. Apply dielectric grease to every connection, especially if you camp near oceans where salt air accelerates corrosion.
Never skip the charge controller. Connecting panels directly to batteries seems like a money-saving shortcut until you cook $1,000 worth of lithium cells. Even small 100W panels output 22V in full sun, far exceeding the 14.4V maximum for most batteries.
MPPT controllers outperform PWM types by 20-30% in real conditions, making the extra $50-100 investment worthwhile for any system over 200W.
Fuse placement saves RVs. Install fuses within 18 inches of battery positive terminals. Use marine-grade DC fuses, not household AC breakers which can’t properly extinguish DC arcs. Size fuses at 125% of maximum current: a 400W system at 12V pulls 33A peak, requiring a 40A fuse.
Panel mounting affects both safety and efficiency. Solar panels lose approximately 0.5% output per degree above 77°F. Mount panels with at least 2 inches of airflow gap using aluminum brackets. This cooling effect alone can increase daily harvest by 10-15% in hot climates.
Wire gauge determines how much power actually reaches your batteries. For 400W systems, use minimum 10AWG wire for runs under 30 feet, stepping up to 8AWG for longer distances. Calculate exact requirements using voltage drop calculators—3% loss maximum from panels to controller, 1% from controller to battery.
Real-World Power Management
Understanding your actual consumption prevents oversizing or undersizing your system. Most couples boondocking use 50-100Ah daily without air conditioning. This includes LED lights (5Ah), water pump (3Ah), phone/laptop charging (10Ah), and a 12V refrigerator (30-40Ah). A 400W solar array replaces this consumption with 4-5 hours of decent sunlight.
Cloudy days cut production by 60-80%. Plan accordingly.
Your location matters tremendously. Arizona delivers 6-7 peak sun hours in summer, while Seattle manages only 2-3 hours in winter. The National Renewable Energy Laboratory provides detailed solar maps showing monthly averages for any location.
Battery capacity should equal 2-3 days of consumption minimum. This buffer handles cloudy stretches without damaging deep discharge. Lithium batteries tolerate 80-90% discharge, while AGM batteries suffer permanent damage below 50% charge.
Inverter sizing depends on your largest loads. A 2000W pure sine wave inverter runs most household appliances including microwaves, hair dryers, and coffee makers. However, these high-draw devices quickly deplete batteries. Air conditioners require 3000W+ inverters and substantial battery banks, typically 400Ah lithium minimum.
Temperature impacts every component in your solar system. Batteries lose capacity in cold weather—lead-acid drops 50% at 0°F while lithium maintains 70%. Solar panels actually produce more power in cold conditions due to improved semiconductor efficiency, gaining 10-15% output at 32°F versus 77°F.
Monitoring tools reveal system performance and problems. Basic voltmeters show battery state but miss important details. Dedicated battery monitors track amp-hours consumed and replaced, providing accurate state-of-charge readings. Bluetooth models transmit data to smartphones, enabling monitoring from inside your RV.
Load management extends battery life between charges. Phantom loads consume power continuously—propane detectors, stereos, and inverters in standby mode collectively draw 1-2A. Install battery disconnect switches for unused circuits. LED bulbs reduce lighting consumption by 80% compared to incandescent. Propane appliances eliminate electrical consumption entirely for cooking, heating, and refrigeration.

FAQs
- How many watts do I need for boondocking? Calculate daily amp-hour consumption, then multiply by 2 for minimum solar watts. Most couples use 50-100Ah daily, requiring 200-400W. Add 50% more capacity if running air conditioning.
- Can I mix different wattage panels? Yes, with proper wiring. Series connections require matching current ratings. Parallel connections work with different wattages if voltages match. Mixed panels may need separate controllers or blocking diodes to prevent reverse current flow.
- Do portable panels wear out from frequent setup? Quality suitcase panels withstand thousands of fold cycles. Inspect hinges monthly and store flat to prevent frame warping. Cable failures occur more frequently than panel damage—leave slack in connections and secure with velcro rather than tight zip-ties.
