Get All The Power You Paid

Solar panels...You bought them, and they were expensive. But are you really getting the power you paid for? Be certain with the state-of-the-art Power Advantage 30 Battery Charger!

Power Advantage 30 features include...

• Maximum power tracking: Continuously adjusts current from solar panels as it transforms voltage, allowing it to seek the precise point where maximum power is available. This produces 25% more power than conventional models.

• 3 charging modes: Bulk charge, constant voltage and equalize.

• Tracks power you produced and used, battery condition, and battery life based on present load.

• Flash memory stores 45 days of data which can be accessed from a PC or modem.

• Enables importing data onto a spreadsheet for further analysis.

• Available in 24 and 48 volt models with up to 1500 watts of power.

• Optional LCD enables continuous system monitoring without a PC.

To be sure your getting all the power you paid for, we invite you to contact us or the Dealer in your area.

Statpower's PROsine™ 2.5 KW Inverter/Charger

Tested by Richard Perez, Joe Schwartz, and Sam Coleman

©1999 Richard Perez, Joe Schwartz, and Sam Coleman

This small inverter/charger beats the pants off other sine wave inverters that cost hundreds of dollars more and weigh three times as much. The Statpower PROsine™ 2.5 KW Inverter/Charger makes cleaner and more reliable power than any utility or generator.

Shipping Container and Documentation

The PROsine 2.5 arrived at Home Power intact via UPS, in a rugged shipping carton. The documentation provided with this inverter/charger is outstanding. The docs came in three parts—a Quick Installation Guide for impatient installers, an Installation Manual, and an Owner's Manual.

The Quick Installation Guide is profusely illustrated with photos. It was all we needed to get the inverter installed and working. The 22 page Installation Guide covers all the material in the Quick Installation Guide. It's more thorough and contains many bits of line art to help the novice installer get everything properly and safely wired up. The Owner's Manual is 27 pages long and covers the actual operation of the inverter and charger.

We had no problems understanding the installation and operation instructions. Too much information, poorly presented, can be worse than not enough information. Statpower has done a great job with their documentation—the information supplied was complete, well organized, and easy to understand.

PROsine 2.5 Inverter/Charger Data

This is a pure sine wave inverter. Its single sine wave cycle has 667 steps—far more steps than other "sine" wave inverters employ. Many steps in the sine wave synthesis coupled with analog filtration yields power of higher purity.

The PROsine 2.5 is physically small for a high performance inverter. The unit measures 20 inches high by 15 inches wide by 5.5 inches deep (51 by 38 by 14 cm) and weighs 32 pounds (14.5 kg). This inverter/charger is far smaller and lighter than 2.5 KW sine wave models made by other manufacturers. Inverter weight and size is largely a function of transformer size. Statpower's high frequency switching power supply design requires a much smaller transformer than traditional 60 Hz inverters. (See HP36, page 36 for a detailed explanation and comparison of inverter designs.)

The PROsine 2.5 comes with a remote control and instrumentation panel and enough wire to mount it 50 feet (15.2 m) from the inverter. This distance can easily be increased to 100 feet with a standard four-wire telephone extension cord.

The PROsine 2.5 is rated at 2,500 watts output with a surge rating of 4,000 watts. Input voltage range is 10-16 VDC. Statpower also makes 24 VDC models of this inverter. The battery charger has a maximum rated output current of 100 amps. This inverter consumes less than 3 watts in search mode. Transfer time from AC source to inverter operation is 20 milliseconds. The unit has automatic overload protection, short circuit protection, and reverse polarity protection via an internal fuse. This inverter is not designed for synchronous operation, selling power to an electric utility. It is designed as a stand-alone unit in both on-grid or off-grid applications.

Installation and Test System

Joe Schwartz did the actual installation late in September of 1998. He attached the inverter to the wall of our battery room and connected it to DC power at the main bus of our Ananda Power Center with two 4/0 (107 mm2) copper cables. The inverter is protected on its DC input with an Ananda 400 ampere Big Switch and a 400 ampere Class-T fuse. The entire installation took less than two hours.

The PROsine 2.5 is fed by a 1,640 ampere-hour, 12 VDC Surrette lead-acid battery. This battery is charged by about 1.8 KW of PVs and a 1 KW wind generator. We also have two backup generators in the system—a Honda ES6500 120/240 VAC generator and a 100 ampere, 12 VDC Genny DeeCee.

Joe found the installation easy and straightforward. He commented that the unit's light weight made it much easier to install than some other sine wave inverters. The light weight and compact size of this inverter make it a natural choice for RVs and boats, or anywhere where space is tight.

Joe wired the 117 VAC input to the inverter using 8 gauge (8.4 mm2) SO cord and a heavy duty three-wire plug. He connected the inverter output to a distribution panel with 8 gauge wire. The control and instrument panel simply plugged in with its RJ-11 phone jack.
