LiFePO4 Home/Biz Solar Battery System 48volt 1,000 A/Hr (51.2v 51.2Kw) LAST ONE

  
I had 40 to begin with and this is the last one!! NEW in the crate, I had 20 of these and this is now the last one.

A complete 51,000-watt (51Kw) LiFePO4 (Lithium iron Phosphate) Battery System. These are 51.2v systems designed to be used in 48-volt systems for home or business systems. Each rack holds five 51.2-volt 200A/Hr (16S1P51.2 volt) self-contained battery systems, the controller at the top communicates with the five battery systems and controls them all. This is a whole house or whole business type that is designed to be self-regulating. Once it is set up the controller monitors charge, discharge of the batteries, voltage, amperage, temperature, cell to cell battery voltage and more.

The controller does not let you damage the batteries and protects them so that they can meet their design life of 20years. If you have a larger power need, two or three systems can be paralleled for double or tripled the reserve ability. There is a touch screen monitor on the front and the system is WiFi enabled for remote monitoring.

This unit can provide a peak of 500 Amp discharge with automatic Discharge Cut-off Voltage of 44 volts. Maximum charging is 300 Amps. All that you need to do is set the solar controller to output 56.5 volts at all times and this system will regulate the charging as needed with no outside touching. Assuming once per day charge/discharge cycle you will get 5000 cycles at a 50% depth of discharge which is over a 13-year life. With a 40% depth of discharge, you will get over 7500 cycles which is 20-year life, your solar panels will only last 20 to 25 years!

Lithium iron phosphate batteries are highly safe unlike Lithium-ion batteries which can be a huge safety hazard leading to explosions and fires. Lithium iron phosphate batteries are much safer because they are cobalt-free making them have low toxicity, they have long cycle life, do not flame, or burn when over charged or physically or mechanically abused.

After all, do you want an outright fire hazard in your house? Is LiFePO4 the same as lithium ion?

The LiFePO4 battery has a cycle life of over 4x that of lithium ion polymer batteries. Well, for starters, LiFePO4 batteries are incredibly efficient compared to traditional batteries. Not only that, they're super-light and you can use most of your battery's capacity without any problems. You can only use roughly 50% with lead acid batteries. After that, the battery gets damaged. So overall, yes, very much so - LiFePO4 batteries are great. LiFePO4 batteries are the safest of the lithium batteries, because they will not catch fire, and won't even overheat. Even if you puncture the battery it will not catch fire. This is a massive upgrade over other lithium batteries, which can overheat and catch fire.

Is LiFePO4 better than lithium ion? The LiFePO4 battery has the edge over lithium ion, both in terms of cycle life (it lasts 4-5x longer), and safety. This is a key advantage because lithium ion batteries can overheat and even catch fire, while LiFePO4 does not.

Why is LiFePO4 so expensive? LiFePO4 batteries are usually more expensive on the front end, but cheaper long term because they last so long. They cost more up front because the materials used to build them are more expensive. But people still choose them over other batteries.

For example, they're much lighter than lead acid and many other battery types. They're also much safer, they last longer, and require no maintenance.
