Take a breath
Outright rejections are rare. Most of what looks like a "rejection" is actually a conditional offer where the DNO wants you to change something (usually export capacity or protection settings) before they approve.
Our team reviews every rejection or conditional offer and lets you know your options.
The four most common reasons
1. Export capacity exceeds what the local network can accept
Fix: Accept a lower export limit, or install an export limitation device.
2. The local substation is already at capacity
Fix: Sometimes solvable with export limitation to zero. Sometimes requires a network reinforcement quote from the DNO (this can be costly).
3. Voltage rise concerns
Fix: Reduce inverter size, use power factor correction, or accept an export limit.
4. Documentation issues
Fix: Usually a re-submit with the correct paperwork.
Your options
- Accept the conditions. Sign a revised offer letter with the DNO's proposed limits.
- Redesign the system. Smaller inverter, add battery storage, add export limitation.
- Appeal. For clear technical errors, we can push back on your behalf.
- Reinforcement quote. For large systems, the DNO can quote for network upgrades. Expensive but sometimes worth it for commercial jobs.
- Walk away. Rare, but for very constrained networks, sometimes the site is not viable.
