What WattWealth Can and Cannot Control

Battery Charging and Discharging Strategy

WattWealth’s primary function is to decide when your battery should:

• ◦Charge from the grid
• ◦Discharge to support household consumption
• ◦Remain idle

These decisions are made using:

• ◦Day-ahead electricity prices
• ◦Battery capacity and state of charge
• ◦Inverter and system limits
• ◦User-defined preferences

The result is a next-day battery plan focused on reducing electricity costs and avoiding unnecessary grid peaks.

Economic Optimization Logic

WattWealth translates raw spot prices into actual household costs, factoring in:

• ◦Taxes
• ◦Grid fees (including capacity-based components)
• ◦Electricity contract structure

This allows optimization based on what you pay, not just market headlines.

Safety-Aware Operation

WattWealth respects all technical boundaries reported by the inverter and battery:

• ◦Maximum charge/discharge power
• ◦Minimum and maximum state of charge
• ◦Temperature and operational constraints

If the hardware reports a limitation, WattWealth adapts—rather than forcing behavior.

Grid Interaction Outcomes

While WattWealth can reduce peak imports and shift consumption to cheaper hours, it cannot:

• ◦Eliminate grid fees entirely
• ◦Guarantee a specific network tariff outcome

Grid operators define tariff rules; WattWealth works within them.

Solar Self-Consumption

WattWealth can improve how solar energy is stored and used by:

• ◦Preserving battery capacity for daytime production
• ◦Avoiding unnecessary grid charging when solar is expected

However, it cannot:

• ◦Increase solar production
• ◦Change weather conditions
• ◦Override inverter-level solar priorities

Electricity Market Prices

WattWealth reacts to market prices—it does not set them.

• ◦Sudden price spikes
• ◦Negative prices
• ◦Market interventions
• ◦Network issues

These are external realities, not software limitations.

Grid Availability and Power Outages

WattWealth does not control:

• ◦Grid stability
• ◦Power cuts
• ◦Regional congestion

Backup power functionality (EPS or island mode) depends entirely on:

• ◦Inverter design
• ◦Electrical installation
• ◦Local regulations

Hardware Installation and Electrical Design

WattWealth assumes a correctly installed and commissioned system.

It cannot fix:

• ◦Incorrect wiring
• ◦Undersized fuses or cables
• ◦Misconfigured inverter settings

These remain the responsibility of the installer and system owner.

Physical Battery Limits

No software can change:

• ◦Battery degradation over time
• ◦Round-trip efficiency losses
• ◦Energy capacity limits

WattWealth optimizes usage, not battery chemistry.
