Can I upgrade my (dead) 1000 for a new 1800 with the existing wiring/batteries???Would be a simple switch out as the boxes are essentially the same.Also does anyone have any comments on the newer HF models?thanx!

Generally, yes. If you are planning to run more stuff with the larger inverter you may need to add some battery capacity and hopefully, you are installing an inverter/charger to be able to recharge that larger battery bank.Take a look at the installation instructions on line and compare it to your current installation. The run from the batteries to the inverter needs to be as short as possible and the cables may need to be replaced with thicker ones.

As long as the existing wire meets your needs and is properly fused you should be fine.HF? HF is just a reseller of low end goods. When my Xantrex Prosine 1800 gave up too soon I moved on to GoPower. So far so good.

I pretty much absolutely avoid anything electrical sold by HF after a number of failures and disappointments. Their non-electrical stuff can be alright just so long as the part has minimal moving parts. Open end wrench is OK for example and I've even found that their socket drive wrenches are OK. Nothing more complex tho.They make an excellent metal dust pan for example...heh

are you going to keep the same loads ?no NEW LARGER loads , NO extra loads at the same time ?use the new one, "EXACTLY" the same as the old ?then yes
