BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. Provide ventilation to
outdoors from the battery compartment. The battery enclosure should be designed to prevent
accumulation and concentration of hydrogen gas in “pockets” at the top of the compartment. Vent the
battery compartment from the highest point. A sloped lid can also be used to direct the flow to the vent
opening location.
8. NEVER charge a frozen battery.
9. No terminals or lugs are required for hook-up of the AC wiring. AC wiring must be no less than 10 AWG
gauge copper wire details refer to table 2. Battery cables must be rated for 35mm or higher and should be
no less than table 1. Crimped and sealed copper ring terminal lugs with a HRNB38-8 hole should be used
to connect the battery cables to the DC terminals of the unit. Soldered cable lugs are also acceptable.
10. Be extra cautious when working with metal tools on, or around batteries. The potential exists to drop a
tool and short-circuit the batteries or other electrical parts resulting in sparks that could cause an
explosion.

11. No AC or DC disconnects are provided as an integral part of this unit. Both AC and DC disconnects
must be provided as part of the system installation. See INSTALLATION section of this manual.
12. Fuses are provided as the over current protection of the battery supply.
13. When PV module or panel is exposed to light, it starts to supply high DC voltage, be sure to turn off DC
switch before commencing the maintenance, and make sure the cables from PV panel are properly
sealed after disconnection.
14. GROUNDING INSTRUCTIONS -This battery charger should be connected to a grounded permanent
wiring system. For most installations, the Ground Lug should be bonded to the grounding system at one
(and only one point) in the system. All installations should comply with all national and local codes and
ordinances.
15. AVOID AC output short-circuit; avoid DC input short-circuit and do not connect the mains while DC input
short-circuit
16. Warning: The maintenance information is only to service persons, If the product is used in a manner
which is not covered by the scope of warranty, the protection provided by the product may be impaired.

The unit
1 user’s manual
Basic Configuration
PL20 Series hybrid Inverter is designed to serve as a backup power supply for AC loads. The input power of
PL20 Series hybrid Inverter comes from PV system and AC grid which not only supply power to AC loads but
also charge the battery bank when the power from AC grid or AC generator is present (also known as Line
Mode).
In the event of AC grid (or AC generator) outage, the AC loads can be alternatively powered by PV system (if
the illumination is sufficient) and battery bank.
The following illustrations show basic applications for PL20 Series hybrid Inverter.
Figure 1. Typical Application of PL20 series hybrid Inverter
Page 6

Note: Appliances like Air conditioner needs at least 3 minutes to restart in case of a power shortage occurs
in a way that the power turns off then back on again rapidly (time is required to balance the refrigerant
gas in inside circuit); so in order to protect your Air conditioner, please consult the Air conditioner
manufacturer whether they have already provided time delay function before installing. Otherwise,
Inverter will trig overload fault and shut off its output to protect your appliance but sometimes it is not
enough and your Air conditioner can be damaged internally beyond repair.
Batteries
The unit support 12volt,24volt or 48vlot battery bank. Please wiring battery correctly. Before proceeding,
ensure you have appropriate size batteries for this inverter. The unit can use flooded lead-acid, or sealed
GEL/AGM lead-acid batteries so ensure that your batteries are in one of these categories. PL20 inverter
with built-in MPPT solar controller, for the battery and solar panel connection please refer to figure 2,figure3
and figure4. If with the built-in 48 MPPT 40A solar charge controller, then please configure solar panels
more than 2350W, otherwise it can not reach the maximum charge current, if with the built-in 48 MPPT 60A
solar charge controller, then please configure solar panels more than 3500W, otherwise it can not reach
the maximum charge current.
Note: if you are using a gel battery or a deep cycle battery, please do not use ordinary lead-acid batteries for
use in solar energy systems. This is likely to damage the lead acid battery or to reach the desired
effect.
The battery must be wired to match with the DC input voltage. Recommend to use battery capacity more
than 200AH .

DC Disconnect and Over-Current Protection
For safety and to comply with regulations, battery over-current protection and disconnect devices are
required. Fuses and disconnects must be sized to protect the DC cable size used, and must be rated for DC
operation. Do not use devices rated only for AC service – they will not function properly.
Note that some installation requirements may not require a disconnect device, although over-current
protection is still required.
Battery Cable Connection
Observe Battery Polarity! Place the ring terminal of DC cable over the bolt and directly against the unit’s
battery terminal. Tighten the M8 screw with 6-10 Nm. Do not place anything between the flat part of the
Backup System terminal and the battery cable ring terminal or overheating may occur.
DO NOT APPLY ANY TYPE OF ANTI-OXIDANT PASTE TO TERMINALS UNTIL AFTER THE BATTERY
CABLE WIRING IS TORQUED!!
WARNING: Shock Hazard
Installation must be performed with care for the high battery voltage in series.
Caution!! Do NOT place anything between battery cable ring terminals and terminals on the
inverter. The terminal screw is not designed to carry current.
Apply Anti-oxidant paste to terminals AFTER terminals have been screwed.
Verify that cable lugs are flush with the battery terminals. Tighten battery cables to terminals (6-10 Nm).

APPENDIX A
How to Select and Configure PV Panels
The following parameters can be found in each PV panel’s specification:
P
max
: Max output power (W)
Voc: open-circuit voltage (V)
Isc: short-circuit current (A)
Vmp: max power voltage (V)
Imp: max power current (A)
PV panels can be connected in series or parallel in order to obtain the desired output voltage and current
which meets the inverter’s allowed range.
When connecting PV panels in series, the max voltage and current of the string is
V
string
= V1+V2+V3+V4…
I
string
= I1=I2=I3=I
4
When connecting the above PV string in parallel, the max voltage and current of the total string is
V
total
= V
string1=Vstring2=Vstring3=Vstring4
…
I
total
= I
string1+Istring2+Istring3+Istring4
In either case, the total output power is P
total
= P
panel
X Number of PV panel
The guideline to select and configure PV string is
P
total
shall be equal or slightly larger than the max. capacity of solar battery charger (900W for 3000VA
model and 2600W for 5000VA model). Surplus capacity of PV string does not help the solar charger’s
capacity and only result in higher installation cost.
Total Vmpof the string shall be within the operating voltage range of solar battery charger (60~72V for
3000VA model and 120~144V for 5000VA model are recommended).
Total Impof the string shall be less than the max. input charging current of the solar battery charger (20A
for 3000VA and 30A for 5000VA model)
Total Vocof the string shall be less than the max. PV input voltage of the solar battery charger (75V for
3000VA and 150V for 5000VA model).
Total Iscof the string shall be less than the max. PV input current of the solar battery charger (20A for
3000VA and 35A for 5000VA model).
Example 1 - How to connect 3000VA model to PV panels with the following parameters?
P
max
: 260W
Voc: 37.7V
Isc: 8.89A
Vmp: 30.9V
Imp: 8.42A
(1) The max. PV input power for 3000VA model is 900W,
900W / 260W = 3.46min. 4 PV panels shall be connected.
(2) Best Operating Voltage Range is 60~72V,
Page 27

72V/30.9V = 2.33max. number of PV panel in series is 2.
(3) Max. input charging current is 20A,
20A/8.42A = 2.37
max. number of PV panel in parallel is 2.
(4) Taking (1)~(3) into consideration, the optimized configuration is 2 PV panels in series as a string and
2 strings in parallel, as shown below.
(5) Check again the Vocand Iscof PV string,
Vocof string is 61.8V < 75V (Max. PV Input Voltage)OK
Iscof string is 2 x 8.89A = 17.78A < 20A (Max. PV Input Current)OK
Example 2 - How to connect 5000VA model to PV panels with the following parameters?
P
max
: 260W
Voc: 37.7V
Isc: 8.89A
Vmp: 30.9V
Imp: 8.42A
(1) The max. PV input power for 5000VA model is 2600W,
2600W / 260W = 10min. 10 PV panels shall be connected.
(2) Best Operating Voltage Range is 110~144V,
144V/30.9V = 4.66max. number of PV panel in series is 4.
(3) Max. input charging current is 30A,
30A/8.42A = 3.56
max. number of PV panel in parallel is 3.
(4) Taking (1)~(3) into consideration, the optimized configuration is 4 PV panels in series as a string, and 3
strings in parallel (as shown below).
