Solar Panel Charging a Xantrex XPower Powerpack 1500 Watt Inverter
Question about using a solar panel to recharge a Xantrex XPower Powerpack 802-1500.
Q: "I would like to purchase a Xantrex 802-1500, but can I charge it with a solar panel and would a 40 watt panel do the trick? Do you sell solar panels or would you know which one I would need. Thank you, John D."
Answer: A solar panel can be used to recharge this large capacity, cart mounting 1500 watt power inverter with built-in battery pack. According to the product manual, a 12-volt solar panel rated to produce a maximum of 12 amps can be used to charge XPower 1500 via the DC Power Socket. Once the solar panelâ€™s DC plug is inserted into the DC Power Socket and the solar panel is placed in the sun, XPower 1500 will charge automatically just as with the AC Charger. With direct sunlight, a typical 3 Amp solar panel will charge XPower 1500 in about 24 hours. If the solar panel does not have a regulated output, disconnect it immediately after XPower 1500 is charged.
Remember that a solar panel large enough and with enough power to recharge the unit is quite expensive. For example, we sell the Go Power 110 Watt Solar Kit with Digital Regulator . This would take about 72 hours of direct sunlight to fully recharge the unit AFTER the initial charge. The specs are :Output Power: 110 W. Rated Current: 6.7 A. Rated Voltage 16.5 V. GPR-25 digital regulator Dimensions of panel 62.4 x 26 x 1.5.
There is risk of battery pack damage if you use a solar panel: 1. with an unregulated output 2. with one that exceeds 15 volts DC. 3. with a generator output not intended for battery charging. 4. if you leave a solar panel with an unregulated output connected after charging is complete.
Initial charge is about 36 hours. The 120VAC option is more certain if you don't have lots of sun. Using a 12V DC outlet takes 24 hours to recharge. Using 120VAC takes 6 to 8 hours' time to recharge a 100% discharged battery. Recharging time is based on using the supplied 5 amp charger, or charging from a vehicle lighter socket.
I recommend that you stay in an RV park periodically where you can recharge using AC unless you opt for a very expensive solar panel module. Thanks for your very interesting question. Sincerely, Barbara
