Hi,

Does any one have experience with Xantrex DR1512 or DR2412 inverters? Are they reliable? Are there better alternatives?

I'm planning a system for my off-grid cabin. I'll need an inverter in the 1500 to 2500 range. I understand the DR series inverters are modified sine wave, but it seems a real jump in price for a true sine wave inverter.

Any advice would be appreciated. Thanks,
Rich

    Only real issue with the DR series is that they are going to be discontinued sometime in the Summer of 2008.

    It's not the price you buy them for, it's what appliances will run off the inverter ?

    Motors, transformers, microwave ovens, TV, stereos, CF Lights, are much better off, run from PURE sine wave.

    Electric stove, incandescent bulbs, LED bulbs, almost anything that could run off DC, will run from a mod-sine inverter.

    Running appliances (washer, fans, fridge, etc..) the motor heats up extra hot, and eventually dies from the stress, and they draw extra power form your batteries while running on mod-sine wave.

    One cost-effective option might be a couple of smaller sine wave inverters. One could run all the time, and then switch on the other for large and/or temporary loads.

    Hi Rich. I'm not an expert like the other knowledgeable and very helpful people here, but do have several years living with a DR 2412. As far as reliability, it was one of the reasons I bought mine in the late ‘90’s (still going strong). I run all of our 110 loads with it (microwave, TV, freezer, computer, coffee maker, washer and dishwasher). The only electric appliance we have had fail was our vacuum and it was 9 years old, don't think I can blame that on the mod. sine wave. The microwave does take longer to cook than it does off the generator. There isn't much doubt a pure sine wave would be easer on the electric stuff, but for the extra grand or two one of the same size would cost I can buy a lot of $50 or $60 microwaves at Wal-Mart if they do fail.
    Then there is the issue of efficiency, with mod. sine wave you lose 15% to 20%, but with the money saved you can add more panels and still have money left over.
    Just my two cents.
