18 x Jinko 440W Solar Panels + EcoFlow PowerOcean + Zappi EV Charger
We recently completed a high-performance solar and battery installation in Haringey N8, close to Crouch End in North London, for a homeowner looking to significantly reduce electricity bills and optimise EV charging.
Having previously rewired this property back in 2014, we were asked to return and design a complete solar PV and battery storage system — a great example of long-term client trust and relationship.

About the Property
This semi-detached home in Haringey features a clean east–west roof configuration, ideal for balanced solar generation across the day.
With no shading issues and good roof space, we were able to design a system that spreads production from morning through to evening — particularly important for households charging electric vehicles and using energy later in the day.
Why This System Was Designed This Way
The homeowner had:
High electricity usage
An electric vehicle
Increasing energy costs
A desire to future-proof the property
We designed a system that would:
Deliver strong annual generation
Store surplus solar energy in the EcoFlow battery
Optimise EV charging via the Zappi charger
Reduce grid reliance during peak rate periods
The EcoFlow PowerOcean system was selected for its reliability, clean installation format, modular battery expansion options, and seamless integration with EV charging.
Solar Array – 18 x Jinko 440W Panels
We installed 18 high-efficiency Jinko 440W solar panels, creating a powerful system capable of generating approximately:
5,000 kWh per yearThe east–west layout ensures:
Morning generation from east-facing panels
Afternoon and evening production from west-facing panels
A smoother daily energy curve
This configuration is ideal for North London homes with consistent daily usage.
EcoFlow PowerOcean 5kW Inverter & 5.1kWh Battery
The EcoFlow PowerOcean system provides:
Intelligent solar energy storage
Evening energy usage from battery
App-based monitoring
Future battery expansion capability
The inverter and battery were installed externally for a clean, practical layout that maintains internal space and ventilation safety.
MyEnergi Zappi 7kW EV Charger Integration
To maximise savings, we installed a MyEnergi Zappi 7kW EV charger, allowing the homeowner to:
Charge the EV using surplus solar generation
Reduce grid charging costs
Optimise energy usage throughout the day
This setup creates a fully integrated renewable energy system.
Installation Process
As we originally rewired this property in 2014, we were familiar with the electrical layout and infrastructure.
Key installation elements included:
Clean and secure external inverter and battery mounting
Discreet cable routing
Balanced panel placement across east–west aspects
Full MCS-compliant installation
The result is a neat, professional finish designed for long-term reliability.
Performance & Year 1 Savings
With approximately 5,000 kWh annual generation, this system is expected to deliver:
Estimated Year 1 Savings: £1,143Savings come from:
Reduced grid electricity imports
Smart battery usage during evening demand
Solar-optimised EV charging
Export payments for surplus energy
As electricity prices continue to rise, the value of this system is likely to increase further over time.
