Looking for advice: converter/inverter brands, models etc.?

[SuaveGato]

Hello,
Due to some good advice from this forum THANK YOU, I am looking into replacing my existing "converter" (InteliPower 9100 #PD9140A). From what I understand, the converter converts AC shore power to 12 VDC and assumedly the generator AC power too? (seems odd/wasteful though to have the Generator make DC, invert it to AC, the convert it back to DC? But I digress...) I also understand that the converter charges the onboard batteries ( (2) 12 volt deep cycle marine/RV) but not very well and can easily boil them off?

So, assuming the above, it has been recommended to me to replace my converter with a newer more modern one that will not only convert my AC to DC but also has vastly superior battery charging system. (with de-sulfating mode) And I "think" they also make an all in one Converter/Inverter/battery charger? Is that true and if so, what would be some recommended makes and models for my camper? I don't need a big inverter, maybe 500 watts? I have a generator for when I need "big power" but I need to plug in a CPAP machine all night that runs on AC and maybe some other misc. things like TV, DVR & DISH receiver, laptop etc.

Thanks for any help and info.

Wasn't AIMS the most cursed inverter brand?

I have to correct myself. There ARE solar controller and inverter combos, in grid-tie models. They start somewhere from $1,200. You don't need this.

Here is one for half that. Note the 60a solar controller is limited to 12v panels in parallel by input voltage limit at 30vDC. Also has a 45a charger.

Well both regulators will not bait each other into overcharging if that's what you mean. Having alternate source charging just means the primary source does not have to work as long or hard.

Great! sounds like they are smarter than I am!
Thanks

Anyone know if they make a combo Inverter / Solar control Module?
Thanks,

I doubt. It appears that inverter makers don't care to learn enough about solar charging, and vice versa. You have a small low-end controller already, keep it connected to the battery and it will play along with converter and Charge Wizard. If (IF) your solar part will become more important, i.e. you'll get larger panels and will need a bigger controller, get a bigger and better controller.

Thanks for all of the help everyone... I just ordered the charge wizard from best converters, should be here soon. I did think of another question though. I also just ordered a Sunsaver 6 to connect my 50watt solar panel. How will that work with the 9100 converter & Charge wizard when I'm plugged into shore power? With regard to will both be trying to charge / over charge my batteries?

Thanks.

1. Clamp the inverter to the battery bank.
2. Unplug your 9100 converter or snap off its circuit breaker if it is not sharing that CB with the receptacles.
3. Fridge and water heater on gas (not "auto" so it won't go to AC but stays on gas)
4. Plug your shore power cord into the inverter
5. Enjoy

BRILLIANT! Thanks. I assume I could just pull the two fuses out of my 9100 converter too, if it shares a breaker with AC receptacles?

You will only get a straight answer from Randy. You may not like the answer, you may have difficulty understanding the answer due to your lack of knowledge, but you will receive a straight answer. Wayne

The beauty of 300 watts is that you can use the existing main battery feed to get 12v and then connect the 120v with a small transfer switch. This avoids pulling wire to get power where you need it.

SuaveGato, you have been given some good advice, and a link to a reputable dealer (www.bestconverter.com). You have been to their site, and have an idea as to what they have I really suggest you call and speak to them for their input. They are more current on what is available, than any of us and quite frankly more experience.

Check your CPAP. Many operate off of direct 12 volts DC, so you connect a new dedicated cord to a cigarette lighter plug and power it direct. DOWNSIDE: CPAPS hate 15 volts, so if you go this route to save 13 watts over using the power brick, be sure to disconnect it from the lighter plug BEFORE starting the engine. They also hate voltage transients caused by starter motors. Check with the device OEM to verify.

CPAP and BiPAP internals also HATE anything but pure sine wave AC power. When I tried modified sine wave with my Respironics BiPAP my LCD operating screen tried to display Chinese or Sanscrit I don't know which. It was quickly unplugged. You need a pure sine wave (PSW) inverter. My Respironics requires 55 watts.

I chose a 300 watt quality Pure Sine Wave unit. A Samlex. There are other brands. Many will chime in here with good alternatives. It's easy to go overboard and select an inverter way too big for the amount of battery capacity you ever intend on using. Choose wisely.

PURE SINE x 2 AC operation
Or another option, DC direct. Many newer models are dual power these days. Craig's List often will have CPAP's at VERY reasonable prices due to the fact many people simply won't adjust to the use of one, once diagnosed. I purchased a Respironics with humidifier having only 18 hours on it for $115. I re-set the pressure myself & it is kept in my RV at all times.
