My coach has 2 heart inverters (ems 2800-12volt) they work fine, but have no built in chargers or ac current switching. 1 is dedicated to convection microwave, other for everything else, no a/c.
The problem is that the separate chargers I have are kaput. They are iota dls 75 amp and there are 2 of them to charge the 4 4-d battery bank.
Should I update the inverters to ones that have integral chargers and ac switching or simply replace the chargers with something that has adequate capacity?
Thanks for your help.

Rv surplus has a 3000 watt inverter/switch/charger on their website. hope this helps |

If the inverters you have are working fine, and are doing the
job you need, why replace 'em?
With an external charger, you can use it if the inverter(s) are
working or not... Charge the tow vehicle battery, etc... And
you can use the charger from the shoreline, the inverter, or
the genset.... wherever there's 110v available...
I dunno, but it sounds like a plan to me.... |

Hi Dick,
Check out the Xantrax RS3000 sine wave inverter/charger. It is 12v and supplies 2 legs to your panel. Also has pass through when plugged in to park ower. The charger is 3 stage 150 amp with float and an equalize feature. The system panel allows you to view the current on both legs as well as the amp draw. It also lets you customize your battery bank for precise charging. I have my RS set up to automaticly start my genset when voltages drop below 10.6 volts. This model comes in 2000 watt or 3000 watt. You can view it at www.xantrex.com
Good Luck
Nick-

While we're talking about inverters, has anyone found anything that won't work on modified sine wave? I have a Norelco rotary shaver, non rechargable, that won't work unless it gets a pure sine wave.
During the recent power outage we had here in Washington, I found that compact flourescent bulbs work just fine on even my cheapest 300 watt inverter which puts out what would be more appropriately called modified square wave. I was able to run several CFL equipped table lamps off of the one inverter which was enough to light up most of the house. |

I have 2 Smart Chargers I purchased from Walmart.
They will not run off of my generator, it fries them. My inverter is a 5000 watt mod sine that runs everything but my printer. I recently bought a remote light switch (wireless)at a garage sale and the inverter actually fried it. It will not work at all now. I am looking for a small pure sine inverter to run a dedicated receptical for the printer and recording equiptment. If any body knows of a small inexpensive one let me know, new or used. |

Hi Phil,
TV's are the #1 electronic device to burn out on modified sine wave. They will usually start out making high pitch audiable noises before they burn out completely. Next will be computers, hair dryers, and microwaves.
Good Luck

My ink jet printer would not work at all and my microwave clock did not work for keepint time and my little clock radio/alarm by my bed would not work. Never had any problems with TV or satellite or other electronic equipment.

If you use a noisemaker with auto transfer it probably would be best to get stand alone chargers.
These can easily be replaced if the noisemaker powers the chargers "too early" on start up , and they fail.
Having "all" your eggs in one electric basket is never a grand idea.
Marine charger ratings were posted in the past.

Modified sine wave inverters are actually fine for most applications. However there is sometimes a problem when serving power to a piece of equipment having specific operating frequency in its high frequency power supply. In an efort to reduce cost switching transistors and other componets of narrow operating frequency ranges are used. These problems can be overcome with some inverter modifications to a point but in order to do so the inverter would need to serve a specific load. In this case multible inverts would need to power idividual loads. When all is said and done it is at least as cheap or cheaper price wise and certainly time wise to run the pulse width modulated sine wave inverters when the application requires. Tim |
