2. 2
Problems
● 1.3 bl people without electricity
(source IEA)
● Clean energy arises, increased need
to compensate intermittency
● Residential-small commercial users
want to reduce energy cost and
increase self-consumption from
renewable energy.

3. 3

Advantages

5. 5
AC-link interconnection
RLS35 Standard ESS
● Retrofit existing plant
● Compatibility different
sources
● Standard AC voltage
● No Retrofit
● No Compatibility
● Given DC range only

6. 6
Smaller Battery
Pictures speak louder
than words.
Relink batteries needs 1/9 of volume
compared to gel lead-acid batteries.

7. 7
Lighter Battery
Well, if you need to get fit, choose lead-acid
Relink batteries weight only 1/10 of standard
ones.

8. 8
The Smallest!
Relink Li-ion battery has the highest density
on the market.
Standard Li-ion battery density is 95 Wh/m3.
2.5 kWh standard battery needs a 5U tray vs. 3U tray.

9. 9
Constant Cells Voltage
Relink batteries keep the cells voltage
constant over charging-discharging cycles.
A non-uniform cells voltage reduce the overall battery
performance and lifetime.

10. 10
Longer Lifetime Battery
A gel lead-acid batteries have 500 cycles average lifetime.
Relink batteries can withstand to deep
discharge for 2000-2500 cycles

11. 11
Power modularity
Do you need more power
for your appliances?
No problem, add an
extra inverter.
Upgrade to 7 kW.

Capacity modularity
Do you need to store
more energy?
No problem, add
extra battery tray.
Upgrade up to 15
kWh (6 trays)

Wider Temp Operative Range
Lead-acid batteries ESS has narrow temperature
operating range.
RLS35 can operate in tough environments
without affecting performances

Underlying Magic
Relink RLS35 introduces two innovative concepts
● Power Generation Control (patent pending).
When the grid is missing, the renewable
generator and load keep working.
● Energy Sharing Mode (patent pending).
Plurality of units and renewable generators, in
master-slave configuration, make possible
sharing of energy among users.

15. 15
Power Generation Control
In case of black-out, the system will keep
supplying the loads and appliances as well as will
not disconnect renewable power generators.
If the power generated exceeds the user power
consumption, the CPU is specially controlling the
generators connected reducing their output.

16. 16
Power Generation Control
● No Light
● No Production
● Keep production on
● Supplies the loads

17. 17
Energy Sharing Mode
By means of the Power Generation Control
system the Energy Sharing can be achieved.
A plurality of RLS35 and renewable energy
generators are connected to each other in a
closed system and connected to the public grid in
one single point allowing a sharing of energy
among the users.

18. 18
Energy Sharing Mode
Users with excess production will share energy
to users with excess of consumption, eventually
energy difference can be sold or purchased.
The greater is the number of RLS35
interconnected the lower is the probability that
the system need to buy energy from traders.
