Marine Applications
Siemens Solar Marine Power Kits
provide an easy-to-install, all-in-one package that gets you on the voyage with quiet & reliable energy—fast.
Marine Power Kit components include the high efficiency, single crystaline solar module, a potted 15 amp charge controller, marine grade, 12 awg cable, SS316 or anodized aluminum hardware and an installation guide.
Available in 10, 50, 75, and 100 watt versions, they're suitable for everything from trickle-charging batteries to powering appliances. Their modular structure means that you can add more panels to produce more power—paving your way to complete solar freedom!
Stand-Alone Systems
Characteristics: Battery storage allows operation at night, during bad weather Charge regulator prevents battery overcharging, overdischarging System controls can include circuit protection, remote monitoring Inverter can add AC power, ``soft start", protection circuits.
Typical Applications: RV/boat electric power
PV-Generator Hybrid Systems
Characteristics: Generator plus rectifier allows battery charging for full energy availability in any climate during any season Generator can be gasoline, propane, or diesel "AC Bus" allows direct AC power to loads from generator through transfer switch, while also recharging battery through rectifier "DC Bus" has all power flowing through battery (DC) avoiding complex transfer switching and any ``glitches" in AC power to loads
Typical Applications: Boat/RV with generator
Marine System Design Work Sheet How to use this work sheet:
Estimate your daily power consumption.
Determine the number of modules you need by dividing the total power consumption by the power output from the Marine Power Kit you want to use.
Estimate your daily power consumption:
Complete the information in the table below to estimate your daily power consumption. Each appliance on the list has an approximate power value in amps. If your appliance is not on the list, fill in the information in the blank spaces provided. Multiply the number of amps for each appliance times the number of hours the appliance is in use. Add up the power consumed for all appliances

Note: Minimum and maximum amp-hours/day are based on the availability of 4 (min.) to 5 (max.) hours of sunlight per day. The actual amount of power produced by the system will vary based on the available sunlight.
To determine the number of modules you need, divide your total power consumption (amp-hours/day) by the Marine Power Kit output per day (amp-hours/day).
Number of Marine Power Kits = total power consumption (amp-hours/day) ¸ Marine Power Kit output per day (amp-hours/day)
Use the numbers from the minimum output column if you use your Marine kit year-round. Use the numbers from the maximum output column if you use your Marine kit only during the summer months.
Power consumption ¸ Marine Power Kit output per day = Number of Marine Power Kits
AH/D ¸ AH/D =
Example:
Power consumption ¸ Marine Power Kit output per day = Number of Marine Power Kits
30 amp-hours/day ¸ 16 amp-hours/day = 2 Marine Power Kit 75's
