Off-Grid Solutions

No Grid ? No worries !

Eco Energy and Solar Solutions specialise in the design and installation of Off Grid solar systems using only top quality products with first class installation to ensure you stay powered.

Battery-Box RES10 / PRO10

Spec: Lithium Iron Phosphate Battery. Each module is 2.56kWh / 52V in a 19” 3RU case. Available in RES (IP55) and PRO (IP20) cabinets. Does not need internet.

Applications: Ideal for both grid-connected storage and/or back-up applications as well as remote off-grid applications.

Function: Stores daytime solar energy for use at other times of the day and night. May also store ‘off-peak’ grid energy in certain conditions.

Sizing: Min 1 (2.56kWh). Up to 4 per cabinet (10.24kWh). Max of 8 cabinets (32 batteries) may be connected in parallel (82kWh).

MultiPlus or Quattro Inverter/Charger

Spec: 48V Inverter/Chargers. Models available in sizes from 2.4-12kW continuous supply and 3-15kW for 30min.

Function: This is the primary ‘mini-grid’ creation device. It uses energy from the battery to create the AC grid line. It can also use energy from a generator or AC-Coupled solar systems to re-charge the battery.

May be ‘stacked’ for larger capacity and/or three-phase applications.

Color Control GX or Venus GX

Spec: User interface & control panel, web connectivity and device communications hub.

Function: Control unit and user interface that connects to the BYD BMU as well as all the Victron equipment. It can report system data to Victron’s VRM monitoring portal and/or store data locally on an SD card if internet is not available.

CCGX needs a cable to the router or a WiFi dongle. Venus is already WiFi-enabled.

The CCGX is shown on the following diagrams as it has a colour display screen. The Venus has the same core functionality and may be used instead. The Venus may be interfaced with via it’s on-board WiFi or the LAN it is connected to.

Adding DC-Coupled Solar? Use Victron’s MPPT Regulators

Spec: An extensive range of models are available in the ‘SmartSolar MPPT’ family. The 85A model will handle ~5kW of PV while the 100A model will handle ~6kW.

Function: The MPPT Reguators will allow solar PV to directly charge the batteries on the DC side of the system.

Multiple regulators may be used on one system. Use a VE.Direct cable to connect the regulator to the CCGX or Venus controller.
