    LiFePO4 Capacity - Voltage chart when under load/charge/nil

    With my battery pack... 16S - 8xCATL 310's & 8x280 EVE's Take the full voltage & /16 to get the cell voltages that I use for the calculations.

    LiFePO4 Capacity - Voltage chart when under load/charge/nil

    Working on the data & making some progress... Getting some good results & predictability within the flat part of the curve. This is really just saving me from buying a wifi shunt & having to pull data out of it. So far the logic is... Use static values start/end curve: 3.45v = 95% 3.4v = 90%...

    LiFePO4 Capacity - Voltage chart when under load/charge/nil

    yeah 100%. This chart has been floating about & is quite popular - https://diysolarforum.com/threads/lifepo4-24v-voltage-chart.22388/ I wanted to get something that was closer to realistic conditions. Its not an exact answer - but an answer based on a lot more data & sound research work.

    LiFePO4 Capacity - Voltage chart when under load/charge/nil

    I understand the downside of estimating capacity by voltage etc... There's a few voltage charts around however you get different results depending if the battery is being charged/discharged. If the battery is resting at 50% & you apply a load - the voltage instantly drops, however the capacity...

    Aus Syd - Selling (complete) 24v Setup - (no batteries), <6mo old

    Upgraded my configuration to 48v, so need to ditch all my 24v stuff. Prices are what they cost to purchase new for a reference. 1 x SCC - Victron SmartSolar 100/50 MPPT Solar Charge Controller ($380 AU) 1 x OverKill 8s BMS 100A (Genuine overkill unit) ($148 AU) 1 x JBD 8s BMS 100A (same as...

    Recommended vendors for GTIL inverters?

    +1 on above - they're for Solar Panels not batteries. HOWEVER... the alternative is to use Grid tie micro inverters, you can use batteries as inputs on those & they're also readily available & compliant with local standards. Down side is that they're typically only 300W or so. You can also use...

    Recommended vendors for GTIL inverters?

    Australia - they shipped from China which is out closest. Unsure if some European hubs would be better - but great store none the less

    Australia - Group buy - DEYE 5kw hybrid (Aus approved)

    Correct - it can do that. There's 3 modes: Selling first: Power loads & charge battery, then anything else exports to the Grid (configurable max feed in power). Load power priority is Solar, grid, battery. Zero export to load: only power backup load, dont power house or feed into the grid (uses...

    Adding a battery to a SUN 1000W GTIL

    I thought it was the other way around? Solark was the original company & Deye used their IP & just started to sell them

    Australia - Group buy - DEYE 5kw hybrid (Aus approved)

    I purchased 2 of the 5kw units & it was around the $1800-2k each mark. The 3.6kw units were a hundred or so cheaper from Deye direct - but i'll ping you the details of the AU person that can import them - it will be cheaper than what i paid direct from Deye as he imports other stuff from them.

    Adding a battery to a SUN 1000W GTIL

    100% agree with you, my peak usage is 2-3,000W per phase - so those units would cover it. I have mine paired with a Victron charge controller & everything works well. They are unbeatable value for money & solid performance. There is a 24v unit that appears to be new (230v though) the...

    Australia - Group buy - DEYE 5kw hybrid (Aus approved)

    Pretty sure it was right on $2k landed. I'll PM you his details, he designs Solar powered heat pumps & works with Deye to manufacture them.

    Adding a battery to a SUN 1000W GTIL

    Sorry - yes Solark, which I think is the original - Deye is a copy of those. Dont compare the GTILs to the Deye/Solarks - they are very, very different units - with immensely different capabilities. The GTILs are a superb little unit & a pair of 2,000W units would do 85% of what i need. But...

    Adding a battery to a SUN 1000W GTIL

    Yes, the Deye units have really solid functionality/features. yes they're 230v - i'm based in Australia, for US there's a different brand Solar Ark(?) i think.

    Australia - Group buy - DEYE 5kw hybrid (Aus approved)

    I went with 2 of the SUN-5K-SG03LP1-EU, the other strong option was to go with the smaller SUN-3.6K-SG03LP1-EU. The 5k wasnt too much more & would have capacity to use more appliances and feed in more to cancel out my peak usage. It does require a lot more cable though! Everything is 35A...
