Tell Us What You Need to Power
A bill, load list or site drawing helps us make a useful first assessment. You can begin with a short description.

Four steps, and what each one needs
A quotation is only as good as the load data behind it. These are the inputs that turn a budget estimate into a priced bill of materials.
| Step | What we need | What you get back |
|---|---|---|
| 1. Load and site | Bills, load list, site photos, location | A stated architecture: grid-tied, hybrid or off-grid |
| 2. Outage and backup | Outage frequency, duration, critical loads | Battery power and energy, with the assumption shown |
| 3. Configuration | Voltage, phases, preferred components, OEM needs | A named bill of materials |
| 4. Commercials | Destination port, incoterms, quantity | Priced quotation, validity, lead time and documents list |
Every quotation states its validity period and the assumptions behind it. Figures that depend on a site measurement are marked as estimates.
Five inputs that move the number most
Two enquiries for the same capacity can differ substantially. These are the inputs that explain the difference.
| Input | Effect on price | Note |
|---|---|---|
| Storage capacity | The single largest cost swing | Sized to the critical load and the backup hours, not the total site load |
| Grid behaviour | Decides hybrid or grid-tied | Hybrid adds the battery and a hybrid inverter |
| Component brand | Inverter and cell selection | Named per order; OEM and ODM accepted |
| Site conditions | Mounting, corrosion, wind load | Coastal and cyclonic sites change the mounting specification |
| Quantity and incoterms | Unit price and freight share | MOQ is one set; freight depends on destination port |
Prices are quoted against a confirmed bill of materials. Catalogue figures are for evaluation, not a binding offer.
Better inputs. Better system choices.
Share as much as you know. We will identify the missing technical data before capacity, model or price is confirmed.
- Daily or monthly energy use
- Peak load and motor loads
- Grid phase and voltage
- Backup circuits and duration
- Installation site and destination
