About CMX High voltage Battery pack system
1：Which hybrid inverter your high voltage battery BMS has been communicated
Our high voltage battery BMS has built protocol communication with Growatt, Sofarsolar, Goodwe, INVT, Megarevo etc brand three phase hybrid inverters.
2： Why we use high voltage battery?
High voltage battery always works with three phase hybrid inverters, which need a higher battery output. So we need high voltage battery solution to achieve a bigger kW power.
3： How much total voltage I need?
This depends on inverter battery side specifications. For three hybrid inverter, it is always around 150V to 800V. We just need to consider this HV battery system volatge is in this range.
Applications
Coremax High voltage HV is a high-voltage DC LFP battery system with an operating voltage range between 150V ~ 800V. It is for residential solar & storage applications and works with high voltage single phase or three phase hybrid inverters to achieve solar self-consumption, peak shaving or back-up supply. A battery system consist of controller and battery modules connected in series to achieve a high voltgae.

How many solar batteries do you need to power your home?
Depending on what you want to use your energy storage system for and the characteristics of your household appliances, the number of batteries you'll need can vary widely. There are several questions to answer: how long you'll want to stay battery powered, what kind of production your solar panels get, what appliances you absolutely need to keep on, and the list goes on and on.
While we can't say for certain how many batteries you'll need, we've outlined the steps you can take to start doing that math in our article about how much of your house you can power on batteries. You can also check out our article on going off-grid with solar and batteries, where we do some example math on what it would take to keep your home completely solar and battery powered.
Solar system efficiency
Solar system efficiency is a system-level metric that measures how well your energy storage system (battery + inverter) converts and stores electricity. There are losses associated with any electrical process, meaning you’ll lose some kWh of electricity when you invert it from direct current (DC) electricity to alternating current (AC) electricity, or when you put electricity into a battery and take it out again. A solar battery’s roundtrip efficiency tells you how many units of electricity you’ll get out of a battery for every unit of electricity you put into it.
Chemistry
A battery’s chemistry refers to the primary compound that’s used to store electricity inside the battery. Chemistry may be the most important characteristic to compare since it ultimately determines a lot of the characteristics of batteries listed above. For instance, different lithium ion chemistries may be more power dense–meaning they store more electricity in a smaller amount of space–or may do a better job of cycling–meaning they are able to perform at a higher level for more years. And those are just the differences within lithium-ion chemistries, to say nothing of the differences between lithium ion batteries and lead acid batteries, or vanadium flow batteries, or other experimental battery chemistries. As is the case with most things, different solar battery chemistries come at (often significantly) different price points.
Battery Service life: The LifeSpan.
Battery lifetimes are measured with three different metrics: expected years of operation, expected throughput and expected cycles. A battery's expected throughput and cycles are like a car's mileage warranty. Throughput lets you compare how much electricity you’ll be able to move through your battery over its lifetime. Cycles measure how many times you can charge and discharge a battery.
To convert a battery’s expected or warranted throughput into an expected lifespan, divide the throughput (expressed in kWh) by the usable capacity of the battery to estimate how many full cycles you’ll get from your battery, and divide that number of full cycles by the number of days in the year: a 20,000 kWh throughput warranty on a 10 kWh battery means 2,000 expected cycles, or a cycle per day for 5.5 years.
To convert a battery’s expected or warranted number of cycles into an expected lifespan, divide the number of cycles by the number of days per year: a 4,000 cycle warranty equates to a cycle per day for 11 years.
All solar batteries have to meet certain safety requirements in order to be certified for installation in homes and businesses: every battery that you receive a quote for on EnergySage is safe and meets these safety requirements! There are, however, some battery chemistries that have been tested for safety to different levels, going even beyond the government-mandated safety requirements for batteries, meaning some battery chemistries are slightly safer than others. But the most important thing to remember is that all batteries installed in the US are very safe!
