Hi folks, I received the following info from BigBattery and thought I would post it in case someone is looking in this direction. This is from the 48V Off Grid System they packaged together over the past few months ( FLAMA-48053-G1 48V LAMA - LiFePO4-115Ah-5.3kWh 1 SPF-3000TL-48P Growatt...

For those who use GroWatt's online monitoring setup here in the US... I went to this URL ( https://www.growatt-america.com/ ) and attempted the login. It stated that For a BETTER BROWSING EXPERIENCE WE HAVE ASSIGNED YOU A NEW ADDRESS: http://server-us.growatt.com . Not sure why I would be...

Ok.. Probably a silly question but... My Inverter recommends 8AWG wire for AC Output.. This looks like it should be good for 40 AMPS output then. I am going to Output the Inverter into a Generator Sub Panel which has a 60 AMP Breaker. Do I size the WIRE for the OUTPUT (the 8 AWG) or do I size...

Question for ya.. I notice that the manual for my Inverter says recommended AC Wire Gauge is 8 AWG. Ok.. So If I look around and I find 8 AWG on Amazon which discusses how good it is for Car Audio ..am, I on the correct product?? Is Car Audio pushing High AMPS? Or is it a different Beast...

Hi Folks, I want to connect AC IN from my MAIN Panel to my GROWATT 3000TL via this manner: 40 Amp Breaker (Single Pole) ... Direct Wire into the Inverter. Now.. Is that overkill? The Wire for a 40 Amp Connection (8/3) is pretty beefy and pricey. Is that overkill? I have seen many folks...

Hi Folks, My Inverter (Growatt 3k) recommends a Max of 40 Amp AC input. If I use a 30 Amp Circuit is there any NEGATIVE (besides slower charging) to the battery? I am just using the system as a GRID backup at this point so slower charging won't be an issue (i hope). Thanks

Hi Folks, I just pulled the trigger on a 48V Power Backup system. This includes a Growatt 3000TL LVM Inverter. What I WANT to happen is that the Inverter is connected to the MAIN POWER (200 amp service) to provide power to charge (or keep charged) a 48V battery. I don't have a need for a...

Hi folks, I was looking at this package for a home (on grid) power backup. (https://bigbattery.com/products/48v-off-grid-system/). I assume folks have installed and use the Growatt 3000TL Inverter. Does this Inverter work like a UPS in that it switches to battery when it detects and issue...

Hi Folks. In starting an energy audit i started with the most important (and problematic ) part of my needs..and that is my water well pump. It is a Shallow Well Jet Pump with the following Specs: 115/230v 3/4hp 8.0/4.0 Amps ..per the label. How would you calculate the pumps needs if it...

Hi Folks, So if I desire a Grid backup system, where usage "Should" only be limited each year, which is best, 48v vs 24v. I have read that 48v is more efficient but I thought that if I decide to add a couple solar panels as a emergency charging source 48v would require more of them to do the...
