Invented over 100 years ago by Thomas Edison as a non-polluting and non-consumable alternative to Lead Acid Batteries using no heavy metals! Now manufactured once again worldwide after lead acid battery companies closed Edison's Plant in 1972.
We have sourced NiFe at a competative rate at a little over double our cheap lead acid range and similar to our Rolls battery prices. This makes them a very viable option for long term off grid solutions.
You need 10 cells to make up a 12V bank, 20 cells for a 24V bank and 40 cells for a 48V bank
They have low operation cost, low self-discharge, long cycling life and environmental-friendly. They can withstand deep discharge, wide temperature variations, mechanical & electrical abuses and still show excellent and reliable performance over a long period. The operation life of solar Ni-Fe batteries is 30-40 Years, the working temperature range can be -40°C to 60°C, which is also the longest life battery for the PV system.
For more information on the advantages of NiFE batteries please read our info here
Optional LED fluid level indicator (£10 per cell)
Optional Auto Fill option (£15 per cell)
These have a long lead time as they are made to order and shipped over to us, please allow 2 months for delivery, but for a battery that will out live any other battery if your deciding to go down this route its definitely worth the wait and this is the reason we can keep the prices low.
Designed for rough ambient conditions for stand alone or grid back up operation. Rated to give a power output of 3.0kW or 4.4kW for 30 min.
IP54 protection to allow outdoor installation if required.
High efficiency (>95%);
Low standby & idle consumption (25W/4W);
Operating temperature range of -25 to +60 deg C.
OptiCool system ensures high power in high temperatures by cooling the encapsulated transformer but keeping air ventilation away from coated circuit boards & electronics to ensure high protection for humid or salty atmospheres.
Inverters are used with the Sunny Island Remote Control which gives a single point of operation. One Remote Control is required per cluster of up to three inverters and includes integrated MMC/SD memory card reader to enable updates, transferring of parameter settings, for storing error/events lists, or data logging.
In single-phase systems only one SI3.0M-11 or SI4.4M-11 can be used. Three-phase systems can be achieved using a cluster of three SI3.0M-11 or SI4.4M-11 inverters, multi-cluster systems are not possible with these inverters.
For larger single-phase or multi-cluster 3-phase systems please see the Sunny Island 6.0H/8.0H
Simple to install and commission, the Sunny Home Manager is the ideal solution for simple solar PV array monitoring and intelligent energy management. The unit provides an overview of all the energy flows taking place in the house, displays recommended actions and is able to control loads via SMA radio-controlled sockets automatically.
The device learns the typical consumption pattern of the household and combines this information with a forecast of the plant-specific PV generation.
The powerful measurement solution for intelligent energy management within the SMA Smart Home: The SMA Energy Meter takes phase-exact and balanced electrical measured values as a grid feed-in and purchased electricity meter and communicates these values via Speedwire. Thanks to its ability to quickly acquire measured values, the SMA Energy Meter is the ideal supplier of data for intelligent energy management within the SMA Smart Home. All PV generation data, purchased electricity and grid feed-in can be transmitted via standard Ethernet cable to the Sunny Home Manager, for example, or to the Sunny Boy Smart Energy. This, in turn, facilitates optimal energy monitoring, effective load and battery management and reliable active power limitation at the grid feed-in point while taking self-consumption into account.
Space-saving top-hat rail mounting in household distribution thanks to compact enclosure
Sunny Island systems using the Sunny Remote Control are flexible and easy to operate: to maximize the user convenience, we have moved the control unit out of the inverter. You can now commission and monitor the battery-powered inverters conveniently without having to be standing right in front of the inverter. The Sunny Remote Control can be used at a distance of up to 20 m and processes information from up to three devices. The rotary switch enables intuitive operation. The four-line display gives you information on the current plant status at a glance. An SD card serves as the service interface. Another convincing feature is the simplicity of installing the SRC-20. Just one cable is needed for the electrical connection and communication. Plug it in at both ends – and you are ready for installation, commissioning or plant information.
For use with Sunny Islands SI-2012/2224 & SI-6.0/8.0H. One remote control is needed per system and allows all settings to be made conveniently. Uses a self explanatory menu interface and rotary switch to give a single point of operation even in MultiCluster systems. Clear four line graphic display shows energy flow between the loads, battery and external energy sources together with battery state of charge status, events and errors.
