FROM APPLIANCES TO A SOLAR PLAN
Build a system that fits your life.
Select your location and loads. We'll handle the estimates.
01Choose your system
02Your location & sunlight
Choose a state, then select a city from the alphabetical list. US Census 2025 incorporated places and census-designated places are included; some rural addresses and postal names are not separate places. Solar data is queried for the selected location.

03What do you want to power?
Enter watts from your appliance label. Every added appliance is included; examples are hints only. For cycling loads, use equivalent full-power hours, not time plugged in. US appliances are 120 V or 240 V at 60 Hz.
Add your first appliance to calculate a plan.
04Battery backup
Based on the daily usage of backed-up appliances. Battery module count is calculated automatically using a 51.2 V LiFePO₄ planning profile.
05Your shopping list
Quantities use a reference 200 W panel and 5.12 kWh battery profile. These are procurement targets, not verified Baseltix stock or an approved equipment package.

Follow terminal labels, not color alone. This is an architecture connection concept, not model-specific installation instructions. Do not energize from this drawing.
Design checks & calculation notesDefaults, sources and items to confirm before purchase
Energy defaults: 75% PV-to-load yield, 20% PV reserve, 80% usable battery capacity, 92% battery-to-AC efficiency and 0.9 design power factor. These are planning assumptions, not guaranteed autonomy or recovery after cloudy days.
Off-grid and hybrid use the lowest monthly average sun hours; grid-tied uses the annual average. Near-zero polar winter sun requires alternative charging and a site-specific design. Annual fixed tilt is PVGIS-optimized; seasonal angles are latitude-based references, not recalculated solar yields.
Example panel profile: 200 W, Vmp 20.4 V, Voc 24.3 V, Isc 10.8 A; coefficient magnitudes 0.28%/°C Voc and 0.4%/°C Vmp; temperature envelope −40°C to 70°C cell temperature. MPPT checks run in the background. Substitute actual datasheets before purchase.
Battery profile: 51.2 V / 100 Ah (5.12 kWh), 100 A continuous discharge, 200 A startup and 50 A charge. Module count covers energy and current. Verify actual surge duration, parallel limits, BMS communication and equipment listing.
US output: 60 Hz. Grid/hybrid need 120/240 V split-phase-compatible equipment; off-grid uses 120 V unless backed-up 240 V loads are present. 120 V loads are tentatively balanced between legs. Check branch assignment, per-leg surge capacity, utility permits, local code adoption, grounding and rapid shutdown where required.
