Warik Energy Installation

Warik Energy provide and install Battery Storage Systems, Hybrid Systems, Home or Solar Batteries, and Energy Storage Systems (ESS) , all of which is designed to save the homeowner money on increasing electricity prices.

Our Grid connected battery storage products do vary, but they all have one thing in common. Unlike off-grid systems, these batteries are suitable for grid connected homes. They are designed to give you a level of energy independence and control that solar alone cannot provide.

Batteries With Solar: How Do They Work?

A grid connected battery system works like this:
Photovoltaic (PV) solar panels convert sunlight to direct current (DC) electricity, which is then fed through the solar inverter to create usable alternating current (AC) electricity. AC electricity is then sent to the distribution board, where it is sent to the household appliances that are using electricity at the time, and any surplus electricity is sent to the battery bank to recharge it.
The inverter/charger will stop the solar system from recharging the batteries once they are full, and divert excess solar power not required by your appliances to the mains grid via your meter or your hot water cylinder depending on the system you choose.
When your solar system is not producing electricity, your battery bank will send power to your household appliances. If the battery bank state-of-charge level gets too low your house will simply draw power from the grid as normal.

Battery Storage

How Much Battery Storage Do I Need?

How much battery storage capacity to buy is probably your main consideration, but this depends on a few things:

  • Are you happy just capturing your leftover solar for use at night (instead of exporting it), and you’re not overly fussed if this runs out during the night requiring you to buy grid power again?

  • Or would you prefer enough storage to make it all the way through the night without needing to buy grid power too often?

  • Are you fussed about blackout protection functionality, or is this not so important to you?

  • Or do you like the idea of having something you can expand on allowing you to eventually go off-grid?

    Depending on your answers, then every home has a ‘storage sweet spot’. Here are some further considerations:

  • how much energy you consume at night (especially in winter) tells you how much storage you will need

  • it’s all well and good having this much storage, but only if you have enough ‘spare’ solar to recharge it all

  • if you already have solar, then how much you’ve been exporting to the grid during winter probably tells you how much battery capacity to buy (any more and you won’t have enough solar to recharge it for part of the year anyway)

    If a hybrid system is not quite right for you and you’d rather go off-grid, then there’s nothing stopping you, but we can’t take any chances and will need to ensure you have the right technology, design and capacities needed to survive whatever is thrown at you. Off-Grid Systems have important differences to Hybrid Systems, and are roughly double the cost.


BYD B-Box Battery Storage





The BYD B-Box is a lithium-iron phosphate (LiFePO) battery unit with battery management system (BMS) for use with an external inverter or charger. All systems can be expanded at any time with the battery modules B-Plus 2.5 . In parallel connections, up to 10 kWh (9.8 kWh usable) are possible per battery cabinet. Up to 8 battery cabinets can be combined and can be extended up to 80 kWh (78.4 kWh usable). This battery can be used as an offgrid solution but also in a grid tied solution for energy storage or self consumption. 


• Expandable from 2.5kW to 80kWh
• Additional B-Box 2.5 can be added at anytime giving complete flexibility depending on requirement and budget
• Single and Three Phase Solutions available
• Lithium-Iron Phosphate Battery giving maximum safety and performance (LiFePO4)
• CE and TUV certified BYD B-Plus 2.5 module (U3A1-50P-A) meets the highest safety standards
• Proven for use in telecom, off-grid and energy storage/self consumption applications worldwide

The B-Box 2.5 focuses on flexibility. The modular design allows the desired performance and capacity to be achieved as desired. The B-Plus 2.5 module is the core of the memory. Each B-Plus module is equipped with its own BMS (Battery Management System). This allows the full utilization of the performance even in modules of different age. The housing of the B-Box 2.5 – 10.0 is equipped with a BMU (Battery Management Unit) and can accommodate up to four of the 19 “B-Plus battery modules. A fully equipped housing (B-BOX 10.0) achieves not only 9.8 kWh usable capacity, but also a power of 10 kW. The BMU is the communication interface between the battery modules and the external inverter.

Furthermore, up to eight B-boxes can be connected in parallel. This increases the maximum capacity – flexible in 2.45 kWh steps – to 78.4 kWh (usable). At the same time, the excellent LFP battery technology from BYD shows its full effect. The batteries are well tested and can be found in the E-mobility. Without the battery, some full electric vehicles could drive more than 800,000 kilometers.
