    SolarEdge vs StorEdge

    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...

    Wire Gauge Charts vs Calculators

    Inline Fuses - temp cutoff feature?

    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...

    Pre-energizing Inverters before LiFePO4 connect?

    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...

    Relays: NC vs NO or other solution?

    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...

    BMS Array Cutoff and Bypass Switch

    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...
