That is a good thing, but on paper there is no difference whether it is 24 volts @ 900 AH or 48 volts @ 450 AH. Using the batteries you selected takes the exact same amount, just configured differently. What you will gain is 400% more efficiency in wiring losses by moving up from 24 to 48 volts.
Like I said I did not run all the numbers, just bringing up the point I did not see AC power factor and inverter efficiency accounted for. A lot of people do not understand AC power. For example using easy numbers supplying a 100 watt AC load with a PF of .8 and an inverter efficiency of 90% requires the battery to supply 100 watts / .9 /.8 = 139 watts.
My comments about Evergreen were just a word of caution. But FWIW they will not be sold or absorbed according to reports. The bond holders will move in and liquidate all assets and turn out the lights. There will be no company to honor any warranty, or sell you a like panel as they will likely cease to exist if reports are accurate. For perspective ESLR share price is $1.22, with an EPS of -$1.23. They owe $338 M, a book value of $160 M, profit margin of -92%, and not enough income to even pay the interest on their debt let alone operating expenses and raw materials. Share holders and customer will get nothing, and bond holders will only receive 40-cents on the dollar when liquidated. It is just not pretty, so be careful.
Not sure I understand your logic. With a battery system you will be paying at minimum 10 times more than you would from commercial power over a 30 year period with the initial investment. If you replace the panels will require more expenditures and drive the cost even higher. From a fiscal POV I do not understand that logic. But that is just the engineer in me.
Trojan is not going to go under, they are still profitable. Trojan's problem is they became complacent over decades because there was very little competition. Well now they have a lot of competition and failed to streamline, change ancient technology, so instead they cut quality to remain competitively priced. At best you are only going to get 4 years out of the batteries before having to replace them at higher prices. For long term investment it may well be less expensive to invest in a higher quality battery that can last 10 years even if they cost twice as much up front. After the first 10 years they would save you 25% in capital cost. Again that is the engineer in me looking out for folks money.
