Just curious, are those grid-tie inverters true sine wave inverters? Also, did you have to go through some sort of permit process before connecting your panels etc.?

[Fearlessthinker]

@Caleb6543 Yes, true sinewave with island protection. They are not UL listed currently which is required if one were to try to get netmetering credit with the local utility. The netmetering application is about $600 as the utility needs to install a shut-off switch and a killawatt (round) meter.

[MrSciencePHD]

Tom, the current probe type power sensors are only about 95% accurate. They have a fixed voltage value in their software for the voltage (110, 115, or 120?) where the WANF meter can directly measure the voltage and amperes to calculate watts. Ed.

@MrSciencePHD Ah, good point. I will have to look into that. Thanks.

I use the ones from the shack and they have the highest amount of milli amps sold they are called enercell 2500mAH rechargable Nmh I forgot perfect name? nickel metal hydride. i think that what the chemical make up is not exactly just out standing batteries killer and you can recharge 100 times.

[Fearlessthinker]

@shartne Yeah, good choice for rechargeables but they are 1.2V vs. 1.5V for alkalines, which I neede for many things. My main use is an aviation handheld radio that takes come strong steady power when broadcasting.

@jmotazedi eBay is where I got mine (procells). About 50 cents per cell. These sellers bought in bulk and sell them in lower quantities. Thanks.

[jmotazedi]

Where do buy them

[jmotazedi]

@fearlessthinker how much do these things run and whw

I ordered one of those efergy elite units from the UK (it has the same timed back-light) and it worked pretty good, but was a bit prone to RFI, and eventually failed. (UHF receiver in display unit seems to be dead).

So, I'm now using the TED to monitor power using of my Sanyo ASHP.

Not the best choice I've made, since the TED suffers from interference too.. From CFLs & light dimmers! Ironic, since these are things one might own, if they wanted to save money on electricity! :)

Cheers,
