Instead of discharging the battery, get a high current diode and put it in series (forward direction, of course). It'll drop the voltage by 0.4-0.7 volts without using much of the stored power. If you want to make it a bit more permanent, add a switch across the diode that will handle the current. When the real voltage drops low enough for the inverter, short the diode with the switch.
@davidahmad60906 ай бұрын
Yes, this is a very good sugestión, if it is a high power shotkey diode, the the voltage drop is about 0.4v drop, but on general, power diodes are about 0.9 volt drop. Note, they will need to be heat sinked very well, as they get hot, another option is to use two power diodes in parallel but place very low value resistors in series with each diode, something like a 0.5 ohm 10 watt ceramic resistor.

It's good to see that at least 2/3 of its capacity is usable with standard electronics in a more 'real world' scenario. Sodium Ion batteries are currently forecast to end up about 1/3 cheaper than LiFePO4 once mass produced, so you could just oversize your battery if space isn't an issue. There do appear to be some benefits to the chemistry in home uses, in particular: - better cold tolerance, both in being able to charge below 0 degC and also better discharge characteristics when cold - intrinsically safer (than even LiFePO4 by a small margin) due to being safe to over-discharge because there are no copper deposition issues - potentially higher energy density than LiFePO4. The first commercial generation of cells are below existing LiFePO4 capacities but CATL is claiming that their second gen (due out in about a year) will exceed 200Wh/kg - potential for exceptionally long lifespan. Natron Energy is already claiming 50,000 cycles with their current product. Great video! Thanks for sharing the data. Also, I wonder if you might have squeezed a bit more out of it if you'd tested at constant .5C. Obviously a less useful real world test for a 50ah battery but still interesting.

Ya, und mit an off grid solar arrangement ist running Zee power inverter continuously the float voltage setting can simply be set too a few millivolts below the inverters DC input high voltage cutoff limit und the inverter will be running nearest to maximum efficiency gaining a slight advantage over lithium while actually using more of the available battery energy und lessening Charge Controller working losses by decreasing the current handling resulting in s cooler, longer lasting life of internal components. The top voltage is not much of a consideration in the continuous operating/ loaded inverter system and is actually a benefit with the addition cold proofing specification to boot. That said, the Inverter DC cut out threshold limit is unremarkable without consideration of load. However, in considering DC resistance loads such as heating, incandescent, brush motors - again this SIB technology provides advantages over lithium. SIB technology is at the front of inverter restructuring where higher DC voltage is predetermined by infrastructure: DC voltages should be consistent with AC voltages to increase efficiency: High voltage DC is more efficient than it's equivalent AC voltage by a large margin.

Very good test for some practical use if anyone decides to get sodiums for an RV or camping fridge. The disadvantages are you won't be able to use last 25% and make sure not to charge above 95% but it also has much more advantages over AGM like you can charge them faster, doesn't have to be kept constantly fully charged, 75% of usable capacity is still more than AGM and of course much more cycles out of Sodium. These should be priced just a little bit more than AGM batteries or even same price as salt shouldn't be more expensive than lead and this is the whole concept of these. As for using these batteries for under the bonnet for instead of stop/start batteries I am not sure if that would be ”healthy” for any vehicle with such high voltages bulbs and computers might start blowing up but then once again maybe alternator wouldn't be able to charge these above 80% so it might actually work ok like that.

I already tested NMC and LFP in parallel with great results. Just waiting for an opportunity to do the same with Sodium, but it will probably not be in the near future until mass production hits and prices become available. Sodium can save the day and prevent an inverter shutdown when an LFP main battery is depleted. This is gold when you have no grid and no sun for a longer period, it can really save the day.

thats going to be a problem for lots of electronics like radios and routers, i can see the smoke getting let out 😮

It can be solved by adding a decent 12V regulator powering the 12V loads.

Cloudy 20 degrees here today. lol. Did they use sodium batteries back in the 1930s?
