1 Magnum ME2012 2000W 12VDC modified sine wave inverter

  Above equipment total = $3,406 

Due to the volatility of battery prices please call for current pricing on the following "rest-of-system" components.


6

Surrette S-530 6V 400 amp-hour batteries 
8 #2/0 AWG 12 battery interconnects 
1 set of #2/0 AWG 10 inverter cables
1 200A Sea fuse & block plus one spare fuse
1 mini battery switch

Fifteen hundred watt-hours per day can power a 1/3 HP, 120VAC pump for 1 hour, plus a 20" color TV and VCR for 3 hours, and two compact fluorescent lights for 4 hours.  The batteries will provide four days of back-up (to 50% depth of discharge)at the usage rate of 1500W per day.

Actual performance will vary depending on your local conditions. Prices can change without notice, please call for an up to date system quote.


This is an example system of how much power it will provide and the cost.  These are merely guidelines to assist you; we design power systems specifically to meet YOUR power needs. 
We offer a Solar Electric Design Guide and 150 page Product Catalog for just $10.00--  a boon to your energy library!  These publications are filled with planning & system sizing data, calculating power consumption,  battery care, generator-inverter systems, basic component info on regulators, modules, inverters, batteries; wind generators, RV systems, and battery wiring, among other things.  This will be a good investment for those seriously considering an alternate energy power system.
