Off-grid power, designed around your van.
Tell us how you travel and what you want to power. We’ll build an indicative SkyEnergi + SRNE system around your real-world usage.
Planning tool only. Final cable, fuse, protection and installation requirements must be checked for your specific vehicle.
What are you building?
Vehicle size helps us make sensible recommendations around battery format, charging and available space.
How do you use the van?
This tells us how much battery reserve to build in between opportunities to recharge.
Build your daily power use
First tell us whether you want 230V mains-style power away from hook-up. That choice determines whether the system needs an Inverter Charger. Then add the appliances you actually use so we can calculate the battery demand.
The calculation applies a 92% inverter efficiency allowance to 230V loads and includes a small daily system-overhead allowance for controls, relays and standby consumption.
How much battery reserve do you want?
Now turn your daily appliance use into an actual battery-bank target. We combine your off-grid duration with a reserve margin, then show the minimum calculated capacity before the SkyEnergi product recommendation is applied.
Indicative minimum battery-bank capacity before charging sources and SkyEnergi product/BMS constraints are considered.
How will you recharge?
The charging architecture changes depending on whether you need off-grid 230V power. If an Inverter Charger is required, the SRNE MD1250 or MD12100 manages alternator and solar charging while the Inverter Charger handles hook-up charging. If no Inverter Charger is required, the SRNE SAA1250 3-in-1 combines alternator, solar and 230V hook-up charging in one unit. We also use your normal driving time to estimate how much energy the DC-DC charger can put back each day.
How much control do you want?
Every recommended core component already gives you solid power management. The SRNE ecosystem can add central touchscreen control, accurate shunt monitoring and connected switching.
Ready to build your recommendation?
We’ll combine your appliance-by-appliance energy calculation, autonomy, reserve target, charging sources and peak load into an indicative SkyEnergi / SRNE system.
The result is a planning recommendation, not an installation specification. Cable cross-sections, fuse sizes, isolators, earthing, AC protection, battery mounting, PV arrangement and vehicle-specific requirements must be verified before purchase or installation.
SkyEnergi Touring System
A balanced system for regular off-grid touring.
*Autonomy is an indicative energy balance only. The load calculator applies 92% inverter efficiency to 230V loads, a small system-overhead allowance, estimated solar yield based on 4 peak-sun-hours at 75% system efficiency, and a conservative DC-DC recovery estimate using the lower end of the selected driving-time range. Real performance varies with season, location, shading, alternator output, battery state of charge, temperature, travel pattern and appliance use. Prices shown are indicative including VAT at time of build and may change. The installation hardware figure is an allowance, not a fixed kit price; labour is not included.
