The Hubble AM-2's specs are 5.5k with 5.5K capacity usable, the
warranty covers 3000 cycles at 100% DoD
and charge / discharge at
1C (100A / 4800-5000W ) for
10 years. 16,500kW guaranteed over 3000 cycles, over 10 years.
- Do these things to a Pylontech, and your warranty is gone by-bye (i.e. no life);
- Even one single battery on its own can deliver excellent performance, lower barrier of entry;
- The lifetime (and cycles) can be increased with judicious use, like limiting DoD, temperature and charge and discharge rates.
The Pylontech UP5000's specs are 4.8K with 4.56K usable, the warranty covers 4500 cycles at 95% DoD, charge / discharge at
0.5C (50A / 2400-2500W for
5 years. 20,520kW guaranteed over 4500 cycles, over 5 years.
- As per warranty, you must
- use it is an ESS system, and
- it must cycled on a daily basis, so not exactly a great battery to use for loadshedding only, unless you want to pay 20-30% more for your electricity. and
- it must be used at the specified temperature (25 degrees C). Show me a residential install that has powerful enough climate control to do that?
- A single battery cannot deliver a reasonable discharge rate for a baby 5K inverter, so it needs at least one friend. That's only OK if you can afford multiple of them, which increases the barrier to entry on a low-budget loadshedding system.
- Even if you cycle everyday, how do you use 20,520kW over 5 years?
