The smart way to take back control of your energy bill
Batt+ (mid-approved metering solution)
The compliant way of charging Hybrid PV Systems from Low Rate Tariffs
During the shorter winter days, there may not be enough generation from a PV system to cover the base load of a property or to add significant electrical charge into a Hybrid Battery. To combat this issue and to make the most of your investment, it would be advisable to top up the charge on these batteries with electricity purchased at a lower rate tariff. (economy 7) This stored energy can then be used during periods where higher tariffs are usually charged, making the best use from your system and significantly reducing the return on your investment.
With energy providers increasing electricity costs by up to 14%, the Batt+ is a perfect solution to help reduce energy costs.
Example Additional Savings Assuming that a PV system can only charge the batteries to full capacity during the summer months, and can be topped up by 3kW per day from lower rate tariffs between October and March:
Example energy prices: Day 18p Night 7p Difference = 11p Allowing for 10% losses on battery system 180days x 2.7kW x 11p = £53.46 per year additional saving on users electricity bills.
Why do I need a PVM-CC-Batt?
Until now, there has not been a simple single metering solution which has allowed batteries to charge during off peak tariffs. Most standard MID approved generation meters actually measure in both directions. Therefore, any electricity stored directly from the grid would actually pass back through your generation meter and would show as increased generation. This may sound beneficial as extra revenue could be created, however, the FiT providers would be alerted to the additional generation and would potentially stop paying the FiT payments altogether. matt:e have developed The PVM-CC-Batt with special algorithms to simplify the connection of a Hybrid battery PV system, whilst compliantly allowing the batteries to top up their charge via the grid from low rate tariffs, without any risk of losing out on FiT payments.
