2. APstorage Sea System Introduction
APstorage Sea system is a complete and independent AC coupling storage solution for residential
PV installations. It can be used with any new or already installed PV systems without changing
equipment in place.
Power Conversion System（PCS）
One PCS can be connected to 1~3 battery packs. When 2~3 battery packs are connected,
they need to be connected in parallel (see connection diagram in the Battery User Manual).
APstorage will help home-owners to optimize their utility bill, offering full flexibility to manage
their electrical consumption. Several modes are indeed available (Backup power, residual power
self-use and advanced mode).

2. APstorage Sea System Introduction
2.2 Basic System Architecture
A typical APstorage Sea system includes two main elements:
-Sea System Inverter. The Sea System Inverter is a smart Power Conversion System(PCS).
The PCS includes a build-in ECU (Energy Communication Unit) to ensure monitoring of the
overall system once up and running
-One Battery pack
NOTE: In the APstorage Sea system, the battery is one of the key components.
Therefore, it is necessary to keep the installation environment well ventilated,
please refer to APbattery user manual.

3.2 Select Mounting Location
1. PCS should be installed on a solid surface, where is suitable for PCS’s dimensions
and weight.
2. Do not install PCS in a confined space with no ventilation.
3. If the PCS is installed outside, it should be protected under shelter from direct sunlight or bad
weather conditions (like snow, rain, lightning, etc). Fully shielded installation locations are
preferred.
4. Please try to install APstorage vertically on the wall.
5. Make sure that the PCS is mounted “face-up”: Product logo is visible after installation.
6. Leave enough space around APstorage. The specific requirements are as follows:
WARNING: APstorage Sea system cannot be installed near flammable, explosive or
strong electro-magnetic equipment.

3.3 PCS Installation Steps
①Mark the holes position on the wall and drill holes according to wall type and expansion screws
type.The configured expansion screw is drilled with a diameter of 12mm and a depth of
50-55mm.
②Put the expansion screws into the holes on the wall. Use a wrench to tighten the hex nuts, so
that the expansion screws sleeve are fully expanded. Then remove the hex nuts. Hang the wall
mounting bracket into the expansion screws, and use the hex nuts to fix it firmly. Make sure
that the wall mounting bracket is horizontal after installation.
③Lift the PCS hang it into the wall mounting bracket, and fix the PCS on wall mounting bracket
with the M6×14mm screw.

3.6 PV System to APstorage Pairing
1. Identify the largest maximum single load power rating (kW) that you want to backup, and
select the absolute minimum number of PCS units required to meet the 2017 NEC
690.10->710.15(A) requirements. The maximum allowed number of ELS-5K units that can be
connected in parallel is 2.
2. Based on the estimated backup loads for the user defined time period, calculate the required
energy storage (kWh) capacity and the minimum number of battery required.
3. Refer the Table 1 to calculate the maximum PV system power (PV system 1) to connect to the
backup side, if the total PV system power is larger than Max PV system power, connect the
excess power (PV system 2) to the grid side.
