Physical Installation (Small Commercial Backup); Integrating Batteries (Inverter Powered "Off") - Pylontech M1C-UL9540 User Manual

3.2.4

Physical Installation (Small Commercial Backup)

1.
Use the output from 200A Fused Disconnect (from the grid) for the Grid input connection to the Sol-Ark.
2.
Connect the Load output from the Sol-Ark directly to the Main Service Panel (at least 2/0 AWG).
3.
Connect a Generator (150A @ 120V x3) or AC-Coupled system to the GEN terminal blocks.

Integrating Batteries (Inverter POWERED "OFF")

3.2.5
1.
Connect batteries to the inverter as shown below.
2.
Ensure the external battery disconnect is OFF while connecting batteries, or arcing may occur.
3.
The 30K-3P reaches a maximum of 100A battery charge/discharge when using both battery terminals. When
using one set of terminals, the max battery charge/discharge is 50A.
Do NOT pull actuation levers more than 45 degrees
away from vertical when installing the batt cables.
Danger: Do not connect the positive and negative reversely.
Danger: N'inversez pas la connexion des pôles positif et négatif.
Multi-Terminal Multi Lithium Install
Note: Each pair of battery
terminals is rated for 50A, so
Lithium Batt #1 and Lithium
Batt #2 will each receive up to
50A of charge and discharge.
Check Battery Integration Guide for specific instructions on Closed Loop Comm Integration:

Connecting PV Panels
1.
Sol-Ark has QUADRUPLE (4) MPPTs for four separate PV input pairs (~8 strings)
2.
MAX PV input = 39kW (± 5%) / system | 9.75kW / MPPT | MAX 500V OC PV | MAX I SC /MPPT 44A
(limiting to 36A)
If using the paralleled Lithium
Batts of the same make and
model, then remove "Battery-
Inverter Communications Cable
(Batt #2)".

Warning: Sol-Ark inverter is a High
Voltage Battery system. Do NOT wire
the battery bank to any other
nominal voltage.
Avertissement: L'onduleur Sol-Ark
est un système de batterie haute tension. Ne
connectez PAS le groupe de batteries à une
autre tension nominale.
When using 48V batteries, do not exceed
eight (8) batteries in series.
Stay within the voltage range: MIN
160V~MAX 500V.
Multi-Terminal Single Battery
Install
Use the "Multi-Terminal Single
Battery" install if your single
battery bank has a max
charge/discharge current
>40A, up to a total of 100A.
