The document discusses the use of a hybrid controller in a 150kW photovoltaic system with two diesel generators of 700kVA and 500kVA capacity. It provides details on the system components, including 8 solar inverters of 20kW each for a total PV capacity of 151.2kW. Schematics show the connections of the PV grid, inverters, diesel generators and public grid to the hybrid controller and generator controllers. Guidelines are provided on sensor placement and PV penetration limits based on the load and generator sizes. The hybrid controller allows optimal control and utilization of solar power based on the load and integrates diesel generation when required.

10. what you mean by Maximum PV power ratio is 60/100 ???
The Fuel Save Controller allows a safe and reliable integration of PV into diesel
grids with a penetration of up to 60%.

11.  Example 1:
Normal load : 180kW ; Generator rate is = 270KW
1.Determine the threshold minimum load for diesel generator
This is fine, minimum load is 30% = 30/100 * 270 =81kw
2. The reset will be covered by PV generation
So you can have 70 percent of PV = Normal load 99kW of PV
180KW-81KW=99KW
 Example 2:
Even if your load is 270kW and the Gen is 270kW. The PV will be able to supply
270kW-81kW = 189kW if you have installed a pv plant that can produce that
For SMA, the PV penetration is defined as total pv inverter capacity / total genset
capacity. Any power above the minimum loading, the PV can cater for it, if it's sized
for. As long as there's adequate spinning reserve, the PV can match the genset
capacity - the minimum loading capacity.

14. 1.Technical Data

15. 1.Technical Data

18. 1. InverterConnection:
 use mostly Modbus/TCP and can be connect via Modbus/TCP to Fuel Save Controller.
2. GeneratorConnection:
 Modbus/TCP with the inverter.
 FSC has CAN interface and Modbus/TCP (not Modbus/RTU) interface
3. Power Measurement:
 Not Compatible Geneset: via power measurement. By measurement FSC knows the
actually state and power of each genset and have to regulate the PV power to allow stable
operation of the gensets in each case
 Measuring the public grid and the PV feeder or the load
 Using Current Measurement (Short circuit bridge):
In normal operation it is open. In case of e.g. maintenance the short circuit bridge have to
close to avoid high voltages.

possible to monitor the genset(s) via measurement.
total CT as follow;
 3 CT before Generator 1
 3 CT before Generator 2
 3 CT before before C.B public Grid
 3 CT before CB of PV feeder
 You have to install the CTs for the public grid measurement on the
public grid side on the ATS. If you install the CTS behind the ATS
 For remote monitoring / support you need an PC with teamviewer which has a
connection to FSC: you measure also the gensets via this CTs

23. Woodward Hybrid Controller:

35. ENcombi ApS Industrial Diesel PV Hybrid system:
 The ECpv is a controller that you set up by parameters, no
coding or programming is needed from the operator,
the ECpv does not only connect directly with all major
inverter brands (without any converters as we can do
Modbus RTU and Modbus TCP directly) –
but also to genset controllers directly such as ComAp,
DeepSea and DEIF + major OEM´s like Cummins and CAT
allowing for the least possible modifications to be made
when integrating with existing site infrastructure.

36. ENcombi ApS Industrial Diesel PV Hybrid system:
 standard, the units covers up to 16 PV feeders and
16 mains connections in all variants up tp 16 genset
in all PV/Genset variants.
 Solar (Power export control e.g. Zero Export or
fixed power export.
RRCR can also be couple with the ECpv).
The cost of medium size is around 2000 $ without
HMI and reached 4000 $ with full option.

37. It comes in the below different models:
 ·
 ECpv Logger (Only logging of site data from gensets, solar and grid)
 · ECpv Solar (Power export control e.g. Zero Export or fixed power
export. RRCR can also be couple with the ECpv)
 · ECpv S for PV/Genset plants with up to 100kw solar inverter capacity,
multiple grid/solar feeders and up to 16 gensets
 · ECpv M for PV/Genset plants with up to 500kw solar inverter

38.  Eccloud
ECcloud is the ENcombi web app for live and historical data
visualization and analysis of your PV and PV-Genset plant
 Ecweb
The built-in web server of ECpv that serves as a plug and
play configuration and live data monitoring tool for
your ECpv.

39. Application description:
 ECpv is controlling the produced solar power in a linear way by Modbus
RTU
 communication, to ensure no power is fed in to the grid at any time when
the load is lower than solar production.
 The ECpv is placed close to the utility connection and communicates on
Modbus RTU with the Entes power meter to read the actual power
imported/exported to the utility.
 The inverters are places 100m downstream Power produced from each
inverter is read directly from Modbus RTU communication
 The plant is monitored on PC and mobile device using Ecweb Alarms and
production data are send tocustomer via emails

43. ComAp Hybrid controller” IS-NTC HYBRID”:
 Maximum controllers that can be used on one CAN
bus is 32.
 The number of PV is limited by number of Inverters;
communication gateway UC-7112-LX Plus is able to
managed 16 of Inverters.
 Regarding to the PV inverters ComAp Hybrid
controller can work with all inverters that are able to
communicate over the Modbus and can regulate
their power.

48.  The ideal penetration is between 40–60 %.
 Lower penetration means more fuel is burned and higher
penetration means that expensive battery storage is needed
 The Cloud Forecasting System is a complementary
extension of ComAp ́s hybrid microgrid controller InteliSys
NTC Hybrid, which significantly increases the efficiency of
the site operation while maintaining the high reliability and
safety of power supply provision.
 It is recommended for use in PV-Diesel applications with
high penetration of renewable energy where it significantly
reduces the operational costs by minimizing the Dynamic
Spinning Reserve and thus reducing the diesel consumption
 The Cloud Forecasting System monitors the cloud
movements in a real time and predicts the overall solar
irradiation above the photovoltaic power plant.

53. 5. DEIF ASC 4
 DEIF introduces the Advanced Solar Controller
(ASC), a solution that provides integrated solution
for systems with utility, diesel and solar power
source.
 Stand-alone applications support up to 16 gensets.
Modbus communication included and the hybrid
controller cost is around 3500 $
 The concept of the ASC-4 is to maximise sustainable
power penetration, depending on the total load
demand
 to the hybrid without compromising constraints
such as minimum genset load demand.

54. The ASC-4 supports two types of applications:
1. Power management applications
2. Stand-alone applications
 Power management applications
In the DEIF power management solution, the ASC-4 is
fully integrated in the DEIF Application Configuration
and SuperVision PC tool. The ASC-4 is connected to
the CAN bus that constitutes the internal DEIF power
management communication link. For that reason,
this approach is only applicable if the genset plant is
equipped with AGC-4 or AGC 200 controllers from
DEIF. The DEIF power management system fully
integrates the PV plant and the genset plant. The
ASC-4 can do both pure off-grid, pure grid-tied and a

55. 2. Stand-alone applications
 Based on transducer power readings and hardwired
feedbacks alone, the ASC-4 determines the power
references to the PV plant. This approach can be
applied to integrate PV power in already commissioned
genset plants, whether they are equipped with DEIF
controllers or not. The ASC-4 can do both pure off-grid,
pure grid-tied and a combination of the two.
 The maximum capability of the stand-alone
applications is 16 gensets, one mains and one PV plant.

65. Overall Line Diagram
you measure also the gensets via this CTs

69. Notes:- The continous
operation of the SMA Fuel Save
Controller is mandatory to
ensure a controlled operation
of the solar system even at any
time. Therefore the installation
of an Uninterupted Power
Supply (UPS) in systems where
power supply interuption is
expected (e.g. backup systems)
is strongly recommended.-
Sensors (Voltage- and Current
Measurement) are not in the
scope of SMA

72. Guidelines:
1. The maximum distance for internal FSC measuring is 100m. If the distance is lower it is equal to
connect the FSC near PV feeder or near ATS.
2. If the voltage after ATS und PV feeder is the same you can connect the voltage measurement on the
point which is better for you. No problem form any point.
3. How much PV you injected in diesel based system depends on load data, genset size, public grid
availability, fuel and PV costs. If you send me concrete project data I can suggest you the PV size. An
approximate value (load and genset sizes fits together) in systems without public grid is 60% of the
genset size.
4. If you want to feed in the PV power in the public grid it is important that it is allowed from public grid
side. Additional the PV size is big enough that you have extra PV power. Also in this case we have to
check the economical.
4. If you use DSE8610 with Modbus/TCP we can use the genset controller for monitoring the genset and
do not need the measurement for the gensets measure also the gensets via this
Each genset has a minimum load and only the rest of needed load can supplied by PV power. If the PV
penetration is to high you have much PV power which you cannot use.
Technical it is possible to add more PV power
FSC sends setpoints or stop comments via Modbus/TCP to the inverter
If you use Woodward Easygen 3000 series via Can with FSC – You need to measure only the public grid
and the PV feeder. You have to connect the CTs bevor the ATS on grid side CTs
