I think you are ahead of the game. These are more a future thing & will be incorporated on all devices by mandation. The amount of money you are talking about would be very little IMO. When they are being mass produced they will be minimal cost per device but will have big ramifications for the...

BentleyJ - Thanks for your article. So Far our system has cost US 0.48 cents per unit. We have 42 panels ~300 Watts Each. 18 KW of Batteries Also a Power Transfer Twitch & Inverter for UPS which runs lights, internet, computers, fridges, fans & TV's on power failure. Our Total Cost USD 19,602 It...

Thanks for this: In Australia metal conduit is not required only rigid PVC is required.

For mine I stick to the original plug packs.

I have never seen any use for them in my system. They just add more complexity to the wiring.

You can put microinverters anywhere. I have mine at ground level where I can easily replace, work on them or check them. I put all my microinverters at ground level. Easily accessible. Originally I laid them out but now I just hang them up on a rod. None get hot.

Lowering the current is very hard. I have found I can do without the buck converter since my last post. The Enphase microinver itself only pulls 10 amp 24v DC and puts out 240v @ 200 watts per hour. It should do same at 48v. I picked 24v originally because there are many more devices available...

Yes I have 15 amp fuses at the battery

Hello. I can't see your name anywhere. I am not sure if you are allowed to put lithium batteries inside or near your home. The following is ONLY to give you some ideas. I used the light circuit to do this. I put a power transfer switch on it so that the light circuit could also be on a separate...

I am sure you are right. I have only produced 7,000 kilowatts so far this year. So I don't think I am ever ever going to get to 15,000+ kilowatts. It is definitely an area I don't understand. My bill for this year, so far, is USD $481 we also have a daily supply charge here totalling USD $169...

I am sure you are right.

True. But just for alternate view. The string panels are sized to inverter and you cannot adjust or add panels easily. With micro- inverters you can add panels easily without having to upgrade Envoy or MultiGate etc. If one panel or micro-inverter is giving trouble - nothing else is affected...

Sounds a great setup. I like it.

True. I like the apps that come with Sunny Boy & Enphase. Deye Sun monitoring in the cloud is new to me but I haven't seen them for sale in Australia new or second hand.

I would bring the Miro-inverters down where you can easily check and or replace. Pic below is of sunny boy micro inverters I got for free. Panels are being put on roof in the next week. With Enphase you need an ENVOY With Sunny Boy you need a MULTIGATE Deye Sun & Apsystems I don't know.

I am grid connected. Any excess power from panels or batteries (minimal) goes to grid. Trying to balance on your own excess power is too expensive & complicated. IMO I use 240 Volt dedicated battery changers instead of solar chargers as I think they are better suited to charging LiFePo4 or any...

Mine is similar. I have 1 Envoy micro inverter per battery. You can have as many micro inverters as you like. I have one 24V Battery with 5KW AC capacity running every night for 14 hours @ 300W AC (240 V) Also one 24V Battery with 1.6KW AC Capacity running every night for 14 hours @ 200W AC (240...

One thing for certain there's nothing easy in solar. It's really hard work, considering all the ins & outs, trying to save electricity costs.

Re panels facing East & West. My brother and niece live 1 km apart. His roof faces north and she can only put panels east and west. July's production for Jim's was 688KW and my nieces was 390KW. Both systems are exactly the same spec and age - other than the way the panel's face. The...

It is always a hard calculation Over a certain voltage the MPPT switches off on all MPPT devices as I understand it. The operating range is much higher & wider than the MPPT range.

RRe your micro i Re your Micro Inverters. If you look at this video 4:20 secs in. This is an alternative Micro Inverter setup that might interest you.

My thoughts. Unless you have limited space: If you want to put in tracking systems it is cheaper to put in more panels. If you want to pay someone to wash the panels it is cheaper to put up more panels. If you want to put in optimizers after the original install it is cheaper to put in more...
