Re: [RE-wrenches] Flickering LED lights on and Outback Dual 7248VFXsystem

sorry, in my $.02 worth below I forgot to mention, none of my LEDs are on dimmers. Todd, I have never noticed an issue when using the 2 meter and the LEDs are on. I'll have to keep a keener ear next time. Bill - Original Message - From: toddc...@finestplanet.com To: RE-wrenche

Kevin, What 2 volt battery charger do you use for either SLA and/or flooded deep cycle batteries? What are the specs on it? Availability? We have tried to source a 2 volt charger in the past and the only ones we found were cost prohibitive. Does anyone have any good leads for such an item? Tha

the only ones i have on a dimmer are in the bathroom and they flicker. being we are grid tied (GVFX-3648) and the grid is up, i suspect this is because of a bad dimmer/lamp combo. anyone find the RFI from led lamps a problem? i have to shut all mine off when using the 2 meter ham rig. todd

I have had this same thing happen with a off grid application using SMA SI's it rooted back to programming one inverter was going to sleep and under some loads the lights would flicker and they were over the dinning room table and suspended from a 16 foot ceiling so it lit up the entire room.

Re: [RE-wrenches] Flickering LED lights on and Outback Dual 7248 VFX system

There may also be a technical aspect of the dimmer that's adding to the flicker, depending on the type of dimmer(s) in use. Some dimmers use a device called a "silicon-controlled rectifier" .. or "SCR". They allow only half of the sine wave to pass. Half-wave power wasn't very noticeable when

Thanks folks for the ideas! So far I have advised a few things.I will report back any successes.. Here is the advice I have shared. 1. Get some different makes and models of LED light bulbs to try out 2. Get some different dimmer switches to try out 3. Try some lights on non dimmer ty

Re: [RE-wrenches] Flickering LED lights on and Outback Dual 7248 VFX system

I think it's for sure how fast LEDs react boB. That's why I don't see it with other lighting technologies like CFL etc. But I don't understand a fridge that causes constant flicker when it is on. Too bad it's not easy to just try another fridge! Trying another light is much easier ;-) Dan Fink, E

Re: [RE-wrenches] Flickering LED lights on and Outback Dual 7248 VFX system

Only during Big load surges ? Could it be current limiting and because LEDs are so fast on and off, you notice the drop in momentary voltage ? Any inverter might do that under the right conditions. Just a thought. boB On 1/6/2014 3:45 PM, Dan Fink wrote: I consider LED flicker as very c

Re: [RE-wrenches] Flickering LED lights on and Outback Dual 7248 VFX system

I consider LED flicker as very common when a fridge starts up, but NOT while it's running. Both dimmed and not dimmed LEDs. I see flicker more often on systems with smaller (or aging) battery systems of course. The only particular appliance I have found causing constant flicker here and with my cli

Hi William; I haven't seen any standard really.  I noticed that HUPs switched from 5/16" hardware to 1/4".  I'm old school like you, and prefer 5/16" hardware, however I think if you look at the lbs of compression that the 1/4" bolt can provide, it's still

Friends: We replaced a set of 24 IBE batteries recently. The original set had all batteries with captive cables (and one flag) except one, which had two flags. This made it easy to connect the leads from the BOS: there was a flag on the positive and negative ends. The new set had all b

I finally found a cycle life chart on these: they're rated at 1200 cycles to 80% DOD, and about 2000 cycles @40% DOD. In an "average" off grid system at 12 years old, I'd say they're near the end of their life. In a back up setup, who knows. I've tested systems like this before, I basically turn
