This Morningstar Tristar MPPT 45 was insanely expensive (over $700) in 2010. But it has been a worker. 8 years with 330W of solar on my RV charging lead acid. The last 3 years, with 300W solar on garage, its been charging various lithium banks for the seed warmers, lighted grow house, quite a...
I've been using the big colorful wire gauge chart from Blue Sea.
https://www.bluesea.com/resources/1437
This has been at odds with online calculators that others have been using.
Here is the latest scenario:
25 amps
130 feet (both ways, 65' from array to SCC)
84 volts
The Blue Sea chart...
I am hoping someone can help me find a solution. I am learning about relays and hoping to incorporate one to cut the power between my array and solar charge controller. 400w array, 45A SCC.
My "thought" was to use an NO (normally open) relay but wondering how i would power a "close" in the...
My new DMM with clamp function from Amazon ($39) just arrived. It was recommended as a decent unit by a trusted member here, and it was a glaring hole in my toolbox.
My first thought was to check it against my other 2 DMM's as a sanity check. It didn't go well. So i tested everything that...
Hello
I am looking to install a Schneider Conext SW inverter and am having a hard time conceptualizing the wiring for AC and DC coupled system. Schneider has a separate DC power distribution panel (PDP) and AC PDP).
Long story left out, but the Schneider diagrams are not working for the way my...
I am in the process of installing a Schneider SW4048 with MidNite Solar E-panel in-between my main panel and an existing sub panel (my new critical loads panel).
Its pretty clear that i need to route L1 and L2 from main to SW4048. Return from SW4048 will connect to L1 and L2 in the sub panel...
I've read the posts about folks using an inline resister to pre-energize an inverter before connecting directly to an LiFePO4 bank. (problem was capacitors blew because they received power too quickly). And yes I plan on having a breaker in there so not exactly directly.
Is this still...
I have been messing with this for a few weeks and am stumped about the "AC Couple Smart Charge" feature. It works as written in that it will take AC micro inverter power and charge batteries first and then pass thru the rest to the grid. I turn this feature on with the "AC Coupling" control...
I was testing my battery discharge to get a feel for its performance and cell behavior.
While running 66amps @13v from battery to inverter, my 100amp inline fuse would get hot and "cut out". I say "cut out" because the breaker lever didn't move as i would expect if it "tripped". But the test...
Hello
I am helping a friend with his home system. He used to monitor via his installer but the went belly up several years ago.
Here is what he sent me, it looks like it has all the info but ask away if not.
Thanks for any help!

Here are my PV system details:
Installed Sept. 2016, almost...
I recently commissioned my SW4048 and was setting up with InsightHome. It is connected to grid on AC In and have a sub panel on AC out. 300Ah 48V battery from cells with JBD BMS.
I found that setting inverter mode from split phase master to split phase stand alone appears to work on...
I have been reading everything and learning quite a bit from everybody here, many thanks!
I have completed a couple solar installs including 400 watts on the RV with existing lead acid batteries and a 3kw grid tie system on the house. Now venturing into LiFePO4 for the RV and a stand alone...
I could have added this to quite a few different threads but did not want to hijack anybody's thread.
There have been a few conversations about disconnecting batteries from a SCC while the PV array is still hot/connected. There are several scenarios where a battery could be disconnected from a...
I have micro inverters powering critical loads panel that feeds the AC Out of the SW4048.
With AC Coupled Mode enabled, its supposed to charge my battery connected to the SW.
No matter what the situation, it ONLY passes all the AC coupled power thru to the grid and never charges the battery...
I am helping a Neighbor who is getting quotes for residential solar. He was quoted $30k for 3.6kW system with Solar Edge optimisers (9 400W panels), Solar Edge grid tie inverter.
I recommended a system with a battery for backup and time shifting usage because PG&E jacks up the rate 4-9pm and...
I have a friend who is asking about installing solar on his house. He is anticipating replacing his roof and wondering if solar shingles is a good solution. Not many examples of folks using them on this forum so thought I'd ask.
Some of the search hits are in regards to Tesla's spectrum of...
