Operating mode

The figure below shows the system application scenario of this product. A complete system includes the following parts:
1. Photovoltaic module: convert light energy into DC power, charge the battery through the all-in-one machine, or directly invert it into AC power to supply power to the load.
2. Mains power or generator: connected to the AC input terminal, it can supply power to the load and charge the battery at the same time. If not connected to mains
Or a generator, the system can also operate normally, and the load power supply is provided by batteries and photovoltaic modules at this time.
3. Battery module: The function of the battery module is to ensure the normal power consumption of the system load when the solar energy is insufficient and there is no mains power.
4. Household loads: It can be connected to various household and office loads, including AC loads such as refrigerators, lamps, TVs, fans, and air conditioners.
5. Inverter control integrated machine: the energy conversion device of the whole system.
6. The specific system wiring method is determined by the actual application scenario.

FQA

1. Can batteries be stacked for storage?
Batteries should be stored in a well-ventilated, dry area kept between 40 and 80 degrees Fahrenheit. They should be stored away from direct sunlight, heat sources, and water. Batteries should be stacked so that they're stable and won't be bumped, knocked over or otherwise damaged.

2. What size battery do I need for home storage?
Home storage batteries start at around 2.5-5 kWh in capacity for small systems, up to the larger systems which offer around 13-15 kWh of energy storage.

3. Does stacking batteries increase amps?
Connecting batteries in parallel increases total current capacity by decreasing total resistance, and it also increases overall amp-hour capacity.

4. What happens when you stack batteries?
By connecting two or more batteries in either series, series-parallel, or parallel, you can increase the voltage or amp-hour capacity, or even both; allowing for higher voltage applications or power hungry applications.
