Harris Tip #1
Modified Sine Wave vs True Sine Wave Inverters
Why did I not mention true sine wave inverters in my show ?? Because it does not matter. Modified sine wave works JUST FINE. DO NOT believe all of the stories on the net related to modified sine wave and electronics and regular motors !! Electronics, especially laptops and TVs run PERFECT on modified sine wave inverters. Take it from me, I've done it since the early 1990's. I Steven Harris, do not own one true sine wave inverter nor do I need to spend 3x the money to get one. This web site is about what WORKS.
Harris Tip #2
Cobra VS Whistler & Other Inverters.
Both are low priced inverters. I'm using the 400 & 800 watt Cobra in my video, and the 1600 watt Whistler in the battery video. Both have really great reviews and some negative reviews, mostly from people who don't know what they are doing and plug a coffee pot (huge load 1100+ watts) into a 400 or 800 watt inverter and expect magic to happen. One of the big difference is that most ALL inverters can handle a surge of TWICE their power rating. So 400 can handle 800, 1500 can handle 3000 watts etc... Difference between the two is the amount of time. The Cobra manual says the surge time is 0.1 Seconds. In reality, its probably a second or less. The Whistler is known for handling up to a FULL 10.0 seconds of surge. This is all over the net, but funny, not in their manual. I have to call the factory. This can make the difference between starting your refrigerator or freezer and not starting it. Both are very good low end inverters that will work fine for you in most situations.
Xantrex made a good inverter, but they discontinued their whole line I was using and are only concentrating on more high end inverters now. Duracell liked Xantrex so much they licensed their design and manufacture them under the Duracell name....but they are just not available in volume, only here and there. So I'm stuck with owning, testing, using and presenting to you the Cobra and Whistler inverters.
Harris Tip #3
NEVER EVER buy a worthless "Trickle Charger".
NEVER trust the recharging of your battery bank just to a "Solar Panel". Buy one of these REAL chargers. Computer controlled, 3 stage battery chargers that have the ability to FULLY charge and maintain a marine battery, car battery, golf cart battery etc...
Harris Tip #4
Under NO circumstances would I go lower than a 6 amp battery charger. DO NOT buy 1 or 2 amp 'trickle chargers' EVER. They are not intelligent and they usually end up destroying a battery PLUS they NEVER have the ability to bring a discharged battery back up
