Flood Season Solar Install Checklist for New Installers in Cross River Markets

Picture this: you're a new installer, you've just finished mounting a small solar system for a trader in a Cross River market – maybe Calabar, maybe Ugep – and the first heavy rain of the season comes. The water rises small small, and before you know it, the bottom of your battery box is sitting in muddy water. The trader is calling you, panicking. You don't want that call. So here's a checklist to keep you out of trouble when the floods come.

Why market areas flood differently

Market areas in Cross River are often built on low ground, near drains that can't handle heavy rain. During the rainy season (roughly June to October), water can rise fast. And market stalls are packed tight – one blocked drain affects everybody. As an installer, you must think like water: where will it go, and how high will it get? Your job is to keep the electrical stuff above that line.

Step-by-step checklist for flood-season installs

1. Visit the site before you quote

Don't size a system from a phone call. Go and stand there. Look at:

• The ground level: is the stall on the lowest part of the market? Ask the trader or neighbours how high water reached last year. If they say "e reach my knee", believe them.
• Drainage: are there open drains nearby? Are they blocked with refuse? Water will find its way.
• Roof condition: will the panel mount survive heavy rain and wind? A weak roof can fail and drop panels.

2. Choose a flood-safe mounting height

For panels: mount them on the roof if possible, or on a raised frame. Keep them at least 1 metre above the highest known flood level. If the roof is not an option, build a strong raised platform. Remember: panels are heavy and catch wind – secure them well.

For batteries and inverter: these must stay dry. Put them on a wall bracket or a raised concrete plinth at least 1 metre above flood level. Never place them on the floor. Even a small flood can ruin a battery or inverter.

3. Use an all-in-one unit or plan your separate components carefully

If you're using a traditional setup (separate inverter, battery bank, charge controller), you have more wiring to protect. Each connection is a point where water can cause trouble. An all-in-one solar generator (inverter, battery, charge controller and BMS in one casing) has fewer exposed DC connections and is often easier to mount high on a wall. That can be a real advantage in flood-prone areas. But whichever you choose, the mounting height rule still applies. (You can see typical all-in-one options on our /products page.)

4. Protect your wiring and connections

• Use conduit or trunking for all cables, especially those running low.
• Seal cable entries into the inverter or battery box with silicone or cable glands.
• Keep DC cables as short as possible and route them above flood level.
• Make sure all connections are tight and protected from water spray.

5. Earth and bond properly

Flood water and electricity are a dangerous mix. Proper earthing helps. Drive an earth rod into the ground (if soil allows) and bond all metal parts. If you're not sure, get a qualified electrician to check your earthing. Live electrical work must be done by a qualified person – don't guess.

6. Prepare the trader for the flood

Teach the trader what to do when water starts rising:

• Switch off the system at the breaker (if safe to reach).
• Disconnect panels if possible (but only if you've shown them how, and it's safe).
• Move any loose items (cables, manuals) to higher ground.
• Don't wade into water to touch electrical equipment.

7. After the flood: inspection checklist

When the water goes down, don't just switch on. Check:

• Any signs of water inside the inverter or battery casing? If yes, don't power on. Call a professional.
• Are cables still intact? Look for cracks or exposed wires.
• Is the mounting still secure? Flood water can weaken supports.
• Clean any mud off panels (gently, with water and a soft brush) – mud blocks sunlight.

If in doubt, replace damaged components. A water-damaged battery can fail or catch fire later.

Common mistakes new installers make

• Mounting the inverter low because it's easier to reach. Easy now, expensive later.
• Ignoring local knowledge: ask the trader where water reached last year.
• Using undersized cable that gets hot and is more vulnerable to water damage.
• Forgetting about motor surges: if the trader runs a freezer or pump, the startup surge can be 2-3 times the running watts. Size your inverter and battery for that surge, not just the running load.

A note on sizing

Flood protection is one thing; correct sizing is another. Don't guess watt-hours. A fan (about 70W) running 8 hours uses 560Wh. A freezer (150W running, maybe 450W surge) running 24 hours uses 3,600Wh. Add them up, then add margin. If you're not confident, use a free sizing tool like /powermatch to check your maths. And if the trader's budget is tight, mention /paysmallsmall – instalments over 2-4 months can make a properly sized system affordable.

Final thought

Flood season in Cross River is not the time to cut corners. Mount high, seal well, and teach the user. Your reputation as an installer is built on systems that survive the rain. Before your next market job, walk the site, check the flood line, and plan your mounting height. If you're ever unsure, bring in a qualified person for the electrical connections – it's better to ask than to explain a fire.
