Inverters for my MH

Yep,

I had 405 watts for solar. My three 12v batteries still went low. Installed four 6V batteries and the solar now maintains. I spent 6 (sunny) days in Quartzite and never ran the genny once. We make coffee on the stove, watch DTV with DVR and have LED lights throughout the RV. Need to turn the DVR off at night as its a pig with power.

Hi Shadow,

Has errors, too. Too much rant to be useful.

Education first Highly opinionated but informative http://handybobsolar.wordpress.com/

IF you want to go on the cheap side, I use a 2Kw inverter from Horrible Freight. Bought it several years ago, and it will run anything I have needed it to, including the microwave. 150 bucks. The inverter is within a foot of the batteries. The shore power from the RV plugs into the inverter, that way all outlets are live. The only thing you need to watch out for is to turn off the converter and make sure the fridge is set to run on propane, otherwise you will run the batteries down pretty quick.

Hi,

The best inverter that I know of is the MSH-M series

Don't think you have anywhere near the roof for 3000w of solar. Did you mean 300W ?

Hi,

I really doubt that there is room for 3000 watts of panels.


Here is a simple flow chart.

Budget-->Energy Audit-->Battery bank size-->number of watts-->PWM or MPPT.

One rule of thumb is between 60 and 150 watts of panels per 100 amp-hours of storage. The smaller the battery bank the higher the wattage needed (per 100 amp-hours). Here is a link to the rather special spreadsheet which includes an energy audit, that N8GS has created to help size solar battery charging systems!

Make sure you have enough battery to take advantage of the amount of solar you put up there.

The whole system including your usage needs to coordinated.

Most important is to choose an "RV" installer. One that will look at your usage, get up on roof to determine how many panels and of what wattage. You can waste alot of money on solar. And there are alot of people out there with some whacky ideas and they love to share them. Find a reputable installer, preferable one who either handles no products directly or has easy access to all as we do as consumers. In other words "no loyality". I'm just getting solar installed myself in Phoenix. Going full time im May.
