A even though back, I had a problem with the AGM battery bank getting out of balance. Next time use proper competitors to create an article, but I am guessing that then your beloved Tesla battery would no longer be the revolutionary and disruptive” item that you portray it to be. Be a real journalist and do some appropriate investigation. The MPPT operation ought to not be impacted just since its connected to a DC-DC converter or a battery alternatively of an inverter. And lastly, when you choose to write an write-up about battery storage and the greatness that you believe is Tesla, then please create it correctly. Aquions battery is created for utility grid storage with high cycle life and reduce charge efficiency.
This would simplify adding a battery program on the DC side, as all” it’d will need is its own DC-DC and capable of charging from, and feeding into, 350 V DC, and some communication with the inverter to know when to do what. No matter what the intention – be it to energy household things, or to earn earnings by returning power to the grid, the far more potent battery will be far more financially viable. SolarCity appears to think they can take Hawaiians off grid with solar plus storage at grid expenses.
Tesla has emphasized a couple of occasions that a single of the massive positive aspects of this is that it contains everything,” barring the inverter that a solar technique would already have so is pointless to include things like. Adding a battery to an current inverter can’t perform effectively unless it is connected to a separate DC input (some inverters have multiple independent MPPT), or following the MPPT (like in optimizers-primarily based systems).
I was replying to @ZShahan3:disqus’s claim that the Tesla battery can basically be tied to an existing PV inverter. I cause that this is here so that any solar PV string can be hooked up to the battery and nonetheless charge the battery to the right voltage. That sounds more and more like if you already have solar and a SolarEdge inverter, you are most of the way there.
Even so, and this is important, value per kWh is truly not proper way to appear at battery pricing – rather, 1 need to look at the levelized cost of power over the lifetime of the technique, which can differ depending on the characteristics of the distinct battery chemistry, the application use case, and other variables. Like other individuals quoted, JLM is glad to have enhanced visibility for battery storage and looks forward to enhanced transparency with all providers. Solar inverters also unidirectional — it makes no sense to want to feed energy to the PV array — so will be unable to charge the battery.
