Safety Precautions
Refer to the Operating Manual
There are information of caution, operation and installation,
please read and keep this manual.
Caution: Risk of Electric Shock
Alternating Current (AC) and Direct Current (DC) sources are
connected to this device. To prevent risk of electric shock
during maintenance or installation, please ensure that all AC
and DC connections are disconnected.
Caution: Risk of Electric Shock
Energy is stored inside the device and components, even
when converter is not operating. Wait for 10 minutes before
opening it.
Electric Shock on all Battery circuits
Danger voltage exists on all conductive wires and terminals
of battery circuit. Please protect and prevent touching of
them.
PV modules ONLY
PV (Solar Input) is designed for PV and solar power
conversion only; do not use it for other DC sources and
purpose.
Caution: Risk of Danger
If the Product is used in a manner that is not covered by the
scope of warranty, the protection provided by the product
may be impaired.
10 min.

5
Caution
Must be installed by a competent person
Caution
Do not stay permanently at a distance of less than 30 cm to
this converter. Device generates electromagnetic radiation
could be harmful in such a close range.
Do not Connect Generator in 0n-grid Mode
In this mode, SP VITALITY-S inject power into AC mains, only
grid can be connected to AC mains. If a generator is
connected, the injection may cause damage of generator
Caution: Hot Surface
Some metallic parts of enclosure may be hot during
operation.
Recycle
Do not throw this electronic device into the trash when
discarding. To minimize pollution to environment, please
handle according to local regulations.

Hybrid PV System
Glossary
1. Hybrid/Off-grid PV Inverter: Manager of PV inputs, charging,
discharging and load supplying functions
2. PV panels: Receive sunlight and convert it into electricity
3. Battery Bank: Stores energy from mains and PV inputs
4. Protected Loads: Appliances & devices take AC power from SP
VITALITY-S, especially in blackout
5. Unprotected Loads: Loads supplied by grid or generator (mains)
directly. In case no AC from grid or generator, unprotected loads are
not powered any more. Usually, loads larger than SP VITALITY-S rating
power should be connected here
6. Grid: Public AC utility
7. Generator
1
: Supplies AC power by diesel engine or other means
8. Monitoring Device: A device to monitor system performance by using
RS485

While on-grid operation, do not connect generator

Principles of Operation
Functions
The Hybrid PV system is an intelligent and automatic power manager, it can be
On-grid Power Manager
In places with grid (utility), SP VITALITY-S can manage the power from PV,
grid and battery. For protected loads connected to SP VITALITY-S, during
blackout, SP VITALITY-S can supply power to them from PV and/or batteries.
Off-grid Power Supply
In places without grid, protected loads will be powered by the SP VITALITY-S.
The power may come from PV panels and/or batteries. In case a generator is
connected, whenever power from PV and batteries are not enough, SP
VITALITY-S switches loads to generator directly.
Charge/Discharge Controller
While there is surplus PV power, SP VITALITY-S will direct it to battery; while
PV power is not enough, SP VITALITY-S will supply loads from batteries.
In case you have enabled charging battery from mains, SP VITALITY-S will
charge battery from mains whenever there is no PV power.
UPS
In case AC main is absent, inverter can supply “protected loads” from PV
and/or batteries. There will be about 10mS to take over and transfer the
power from mains.
For very critical loads cannot withstand the time of transfer, please use a “on
line” UPS in between inverter and critical loads.
Working with Grid
There are varieties of connections to work with grid; the differences are the
connections of inverter output and loads.
Off- grid mode
The loads get power EITHER from Mains (Grid or Generator) or inverter
output. Normally, SP VITALITY-S provides power to loads, in abnormal
conditions such as failure, overload and battery is empty; the loads will be
switched to get from mains directly.

This application is suitable for
1Blackout
2With utility, but user DO NOT want to use utility or use utility as a backup
source
In this mode, inverter output is physically separated from grid, therefore, no
power can be injected to grid.
On-grid mode- Net Metering
Inverter is physically connected to grid (mains) directly. The power to loads is
managed to be:
1. From SP VITALITY-S only: In case the power from solar is enough, SP
VITALITY-S converts PV power to loads directly. In addition, surplus
PV power (in addition to charge battery and loads) is fed to grid so
as to reduce the net power demand in certain period
2. From both SP VITALITY-S and grid: While the power from PV is not
enough, SP VITALITY-S and grid share the power

This application is suitable for Surplus PV power can be feed to grid and paid.
On-grid mode- Self Using
In some applications, e.g. grid is weak or feeding grid is not beneficial, surplus
power feeding is not encouraged; the PV power is used by their own. This is
“Self Using”.
The operation principles are the same as “Net Metering” except that surplus
power is not fed to grid.
This application is suitable for PV power can be fed to grid but not paid.
Compensating Loads
2
from Batteries
This SP VITALITY-S can use energy in batteries to compensate power from
mains. This will minimize the power demand from your grid supplier.

Only Protected Loads connected to inverter

Do not Connect Generator in 0n-grid Mode
In this mode, HPV inject power into AC mains, only grid can
be connected to AC mains. If a generator is connected, the
injection may cause damage of generator
Only Hybrid inverter (-D model) can be interactive with grid
For above modes, only –D models can be connected and
interactive with grid. Off-grid inverter can operate in off-grid
mode only.

12
During the night or when no power from PV, inverter will take power from
battery to supply ALL the power demands from “Protected Loads”.
To do this, you have to enable the “BAT-> Load” and disable function in settings
menu.
Power Priority
3
To Loads
The power supplied to loads from different sources follows the priorities.
In off-grid mode, it is
PV -> Battery -> Mains (AC)
In on-grid mode, it is
PV -> Mains (AC) -> Battery
If Battery -> Load function is enabled, it is
PV -> Battery -> Mains (AC)
3
Some customized models may apply different priority, contact your installer to get more
information
BAT -> Load is not allowed for some areas
For some areas, it is not allowed to feed battery power
to/with grid. Please understand your local regulation before
enable this function.

13
To Battery (Charging)
The power charged to batteries from different sources follows the priorities:
PV -> Mains (AC)
